Exhibit 99.2

BioTime’s Subsidiary Cell Cure Neurosciences, Ltd. Provides Update on OpRegen^® Product Development

- Product development on track for IND filing during 2013 -

ALAMEDA, Calif.--(BUSINESS WIRE)--April 23, 2012--BioTime, Inc. (NYSE Amex: BTX) announced today that Charles S. Irving, Ph.D., the CEO of BioTime’s subsidiary Cell Cure Neurosciences, Ltd. will provide an update on the development of OpRegen^® at an investor meeting in New York City. In his presentation, Dr. Irving will describe the unmet medical needs and markets for the treatment of the dry form of age-related macular degeneration (AMD), and the advantages of Cell Cure’s OpRegen which has been produced from human embryonic stem cells in culture conditions free of animal products, eliminating the need for designating the product as a xenotransplantation therapeutic. Dr. Irving will also discuss Cell Cure’s collaboration with Teva Pharmaceutical Industries Ltd., under which Teva has the option to develop and commercialize both OpRegen^® and OpRegen-Plus^®. Dr. Irving will describe the nature of the ongoing preclinical studies which are expected to lead to regulatory filings for the initiation of human clinical trials in 2013. Dr. Irving’s presentation will be available on BioTime’s web site www.biotimeinc.com as well as Cell Cure Neuroscience’s web site at www.cellcureneurosciences.com.

Background.

Age-related macular degeneration is the leading cause of blindness in an aging population. It is widely believed that the loss or dysfunction of a particular type of cell called “retinal pigment epithelial” (RPE) cells is the root cause of the disease. While therapies exist to treat what is called the “wet form” of macular degeneration exist, there are no therapies for the “dry form”. The transplantation of healthy RPE cells may provide a superior treatment for this devastating disorder. Cell Cure’s OpRegen^® is “xeno-free”, meaning that no animal products were used in the culture of the human embryonic stem cell-derived RPE cells. The use animal products to culture cells often results in the designation of the therapy as a “xenotransplantation” product, even though the cells themselves are of human origin. Xenotransplantation may raise purity issues, increasing the costs of product development along with other risks and uncertainties. The production of animal product-free OpRegen^® will therefore eliminate concerns of xenotransplantation and may provide cost savings in development and production should the product successfully complete clinical trials and be approved for human use.

Exhibit 99.3

BioTime’s Subsidiary OncoCyte Corporation Provides Update on PanC-Dx^TM, and Related Diagnostic Products

- PanC-Dx on track for CE Marking in Europe by late 2014 -

ALAMEDA, Calif.--(BUSINESS WIRE)--April 23, 2012--BioTime, Inc. (NYSE Amex: BTX) announced today that Joseph Wagner, Ph.D., the CEO of BioTime’s subsidiary OncoCyte Corporation and Karen B. Chapman, Ph.D., Director of Bioinformatics will provide updates on the development of the Company’s pan-cancer diagnostic PanC-Dx^TM and related diagnostics at an investor meeting in New York City. PanC-Dx^TM is a screening diagnostic that may permit the use of a blood test to screen patients for a number of solid cancer types such as those of the breast, colon, and lung. In his presentation, Dr. Wagner will describe the next-generation cancer diagnostics based on improved technologies in genomics and proteomics. He will also update investors on the planned development timeline of PanC-Dx^TM leading to an anticipated product launch in Europe in late 2014.

Dr. Chapman will describe the process used by OncoCyte to generate the novel markers of cancer. A wide array of normal human cells, normal human tissues, tumor cell lines, and human tumors representing 20 different types of cancer were screened using novel computer algorithms leading to the identification of more than 700 cancer-associated genes, including genes that had not previously been associated with cancer. As a result of this work, more than 20 patent applications have been filed. So far, OncoCyte scientists have screened more than 60 of the marker proteins in blood samples from cancer patients and have assembled a multiplex platform of the most promising markers for cancer diagnosis. Monoclonal antibodies to seven of these markers are currently under development, and OncoCyte plans to test the newly-produced antibodies in blood samples during the next six months. A subset of the markers selected for inclusion in PanC-Dx^TM, have been applied to 50 blood samples and showed 83% sensitivity and 97% specificity in correctly identifying breast cancer, compared to widely-used mammograms that typically show a sensitivity rate of 70-90% and a specificity of 85-93%. OncoCyte expects that the inclusion of additional antibodies will improve the diagnostics sensitivity and specificity further. The relative ease and cost saving associated with a simple blood test may make PanC-Dx an attractive alternative to a mammogram that is more expensive, exposes the patient to radiation, and causes discomfort to the patient.

Dr. Chapman also showed data on an additional novel single marker designated “Marker A” which shows a high association with breast cancers. Initial blood testing shows that the protein associated with Marker A may distinguish breast cancer patients from normal individuals.

Dr. Wagner’s and Dr. Chapman’s presentations will be available for viewing on BioTime’s web site http://www.biotimeinc.com as well as OncoCyte Corporation’s web site at http://www.oncocyte.com/.

Background

There are tens of thousands of genes in the human DNA code. The pattern of genes that are turned on or off determines the behavior of cells in the body. BioTime developed novel methods of accurately determining the pattern of over 40,000 gene sequences expressed in diverse types of cells arising from embryonic stem cells and induced pluripotent stem cells. Working together, BioTime and OncoCyte scientists identified over 700 genes associated with cancer. Of these, those which appeared to be novel cancer-associated genes were chosen for further study.

OncoCyte's scientists subsequently determined that the patterns of the proteins produced from a subset of these genes could be detected in the blood of cancer patients, but not in the blood of healthy people. The percentage of times that the test correctly identified people as cancer-free, which defines the test's specificity, was higher than that of commonly used tests such as the prostate-specific antigen test for prostate cancer. This finding, combined with initial evidence that this prospective screening device may be useful for diagnosing a broad range of cancer types, led BioTime and OncoCyte to prioritize the rapid commercialization of PanC-Dx^TM. Another motivation for this product focus was the rapid growth of the oncology diagnostics market, which according to data from Business Insights, Ltd. is estimated to reach US $8.14 billion by 2014, thus outpacing the growth of the general diagnostics market.

OncoCyte intends to initially develop and market PanC-Dx^TM in Europe before seeking regulatory approvals required to market the product in the United States and other countries. A blood screening test for cancer markers meets the definition of an in vitro diagnostic product as defined in the European Directive on in vitro diagnostic medical devices (IVD). Under this directive, IVD products placed into the European market must bear the CE mark, which indicates the product is in conformity with all applicable requirements of safety, performance, instructions, markings, and quality sufficient for the safe and effective use of the product.

PanC-Dx^TM is classified as a General IVD under the IVD directive. The CE marking process is accomplished by a self-declaration of conformity with the requirements of the directive. Working with the British Standards Institute, OncoCyte will be pursuing full medical device quality system certification, which should be achieved by the fourth quarter of 2014.

About OncoCyte Corporation

OncoCyte Corporation is a majority-owned privately-held subsidiary of BioTime, Inc. OncoCyte's mission is to develop novel products for the diagnosis and treatment of cancer based on embryonic stem cell-derived technology in order to improve both the quality and length of life of cancer patients.

About ReCyte Therapeutics

ReCyte Therapeutics, Inc. is a majority-owned privately-held subsidiary of BioTime, Inc. ReCyte Therapeutics is developing novel pluripotent stem cell-derived products for the regeneration, repair or protection of diseased or injured tissue, with a particular emphasis on age-related vascular and related disorders. Its product candidates are either cellular or acellular (cell-free), depending on the intended clinical indications, and address major unmet medical needs for effective treatments in areas such as coronary disease, heart failure, stroke, and ischemic injury. In one such application, ReCyte Therapeutics is employing its proprietary ReCyte™ induced pluripotent stem cell (iPS) reprogramming technology to reverse developmental aging of human cells. The renewed cells can be used to generate vascular and blood progenitor cells that may be developed as a means of treating a broad variety of disorders. ReCyte Therapeutics has already demonstrated consistent derivations of human endothelial progenitor cells from pluripotent embryonic stem cell lines under cGMP-compatible culture conditions that approach clinically relevant scale.

ReCyte Therapeutics is also characterizing unique secreted products such as trophic factors and extracellular matrix derived from proprietary human embryonic progenitor cell lines. These products may be developed as acellular therapeutics that can “instruct” normal tissue-resident stem cells in patients to regenerate or repair damaged tissues. Additional information on ReCyte Therapeutics can be found on the web at www.recytecorp.com.

Exhibit 99.6

BioTime’s Subsidiary LifeMap Sciences, Inc. Presents Update on Product Development

ALAMEDA, Calif.--(BUSINESS WIRE)--April 23, 2012--BioTime, Inc. (NYSE Amex: BTX) announced today that David Warshawsky, Ph.D., CEO of BioTime’s subsidiary LifeMap Sciences, Inc. will provide and update on product development at an investor meeting in New York City today.

Dr. Warshawsky will describe the origins of XenneX, a company that LifeMap has agreed to acquire, and the business strategy that led to its rapid rise to profitability. He will describe the GeneCards^® database (www.genecards.com) which is used as a research tool world-wide in academia, research hospitals, patent offices, and leading biotech and pharma companies. He will report that GeneCards enjoys more than 12 million page visits/year by hundreds of thousands of unique users, consistently in top positions for gene search results in Google.

Dr. Warshawsky will discuss LifeMap’s work to build an integrated map of the thousands of cell types in human development, beginning with the fertilized egg and ending in the developed human. Combined with genomics information, the database is expected to become a “road atlas” of human biology benefiting medicine and research. In addition, LifeMap is developing its own proprietary technology to effectively analyze data gathered from the data bases for use in the development of cell-based therapies. LifeMap also plans to market a new disease database called “MalaCards,” which has been developed by a world-leading bioinformatics team at the Weizmann Institute of Science in Israel and may be licensed to LifeMap from Yeda Research and Development Company Ltd, the Technology Transfer Company of the Weizmann Institute.

In addition to expanding LifeMap’s data base offerings through the acquisition of XenneX, BioTime plans to make LifeMap the principal marketing subsidiary for BioTime research products, including ACTCellerate™ human progenitor cell lines, GMP human embryonic stem (hES) cell lines, hES cell lines carrying inherited genetic diseases, and ESpan™ growth media for progenitor cell lines for non-therapeutic uses. LifeMap will utilize its databases as part of its on-line marketing strategy to reach life sciences researchers at biotech and pharmaceutical companies and at academic institutions and research hospitals worldwide.

Dr. Warshawsky will explain how, in a therapeutic discovery collaboration with BioTime, LifeMap scientists will utilize LifeMap’s proprietary discovery platform and stem cell data base along with its newly acquired data base products as a discovery platform to aid in the development of ACTCellerate™ human progenitor cell lines into products for the treatment of human diseases, especially degenerative diseases that might be treatable by cell replacement therapies. Human therapeutic products require a high degree of purity to meet the hurdles of regulatory approval and acceptance in medical practice. ACTCellerate™ technology was invented as a means of generating human progenitor cells from hES cells in a scalable and highly purified state. The LifeMap discovery platform will be applied to select the progenitor cell lines that are most likely to be useful in developing cell based regenerative medicine therapies for various diseases.

Dr. Warshawsky’s presentation will be available on BioTime’s web site www.biotimeinc.com as well as LifeMap Sciences' web site at www.lifemapsc.com.
