Cryo-Cell International, Inc. in a study published on Cell Transplantation shows that stem cells found in menstrual blood proliferate rapidly and have significant potential to develop into multiple cell types. Menstrual stem cells offer an easily accessible, non-controversial and renewable stem cell source, and these findings could mean these cells have the potential to one day treat a host of diseases.

The study, "Multipotent Menstrual Blood Stromal Stem Cells: Isolation, Characterization and Differentiation," was conducted by researchers at Cryo- Cell International who originally discovered the stem cells. According to the study, the stem cells in menstrual blood, known as MenSCs, are stromal stem cells, meaning they have the capability to differentiate into important cells, such as such as bone, cartilage, fat, nerve and cardiogenic cells. The study also found that the cells divided rapidly and plentifully, indicating a possible therapeutic value.

With additional studies of the cells in a variety of categories, the use of these cells may lead to treatments for a number of serious diseases, such as osteoporosis, stroke, Alzheimer's and Parkinson's disease. The cells may even one day be used for customized anti-aging or sports medicine treatments.

During the study, the investigators analyzed shed menstrual blood and tissue to identify MenSCs. The samples were obtained using a menstrual cup and transferred to a laboratory for processing. At the lab, the cells were quality control-tested and grown in culture to allow for expansion and to assess their growth capabilities. Further analyses were conducted to assess the cells' ability to differentiate into new cell lines, in order to determine which diseases the cells may be used to treat. The average cell collection from a sample of menstrual blood was approximately five million, of which 75 percent of the cells were considered viable. Importantly, the cells rapidly expanded at a doubling rate of 24-36 hours, starting with 50,000 cells on day one and culminating into 48 million cells in less than one month.

Based on the results of the study, Cryo-Cell is pursuing further research into menstrual stem cells. Cryo-Cell is organizing a number of research and development agreements in efforts to develop promising regenerative therapies utilizing C'elle technology in cardiology, diabetes and neurological diseases. Results from these studies are expected in the next year. The Company is actively seeking to expand its portfolio of research collaborations with scientists worldwide interested in studying this novel stem cell population for regenerative therapeutic development. Cryo-Cell's C'elle(SM) service, which was introduced in November, 2007, is the first available product that enables women to collect menstrual flow containing stem cells, which can then be cryogenically preserved in a manner similar to stem cells from umbilical cord blood.
