What is Stem Cell?

Stem cell is a kind of multipotential cells that have self-renewing ability, that is, they are staying in pending differentiation status and have multiplication capacity. With proper condition or inducement, stem cells can differentiate into various functioning cells or tissues or even organs, so the medical field call them Almighty Cells iconically.

Scientists believe that tissues and organs cultivated by stem cells are of great significance to treatment for cancer and other malignant diseases, which will bring hope to those suffering from diabetes, late-stage liver disease, Alzheimer disease, Parkinsonism, spinal cord injury, etc.

What is Stem Cell

Identification of Stem Cells

Although there is not complete agreement among scientists of how to identify stem cells, most tests are based on making sure that stem cells are undifferentiated and capable of self-renewal. Tests are often conducted in the laboratory to check for these properties.

One way to identify stem cells in a lab, and the standard procedure for testing bone marrow or hematopoietic stem cell (HSC), is by transplanting one cell to save an individual without HSCs. If the stem cell produces new blood and immune cells, it demonstrates its potency.

Clonogenic assays (a laboratory procedure) can also be employed in vitro to test whether single cells can differentiate and self-renew. Researchers may also inspect cells under a microscope to see if they are healthy and undifferentiated or they may examine chromosomes.

To test whether human embryonic stem cells are pluripotent, scientists allow the cells to differentiate spontaneously in cell culture, manipulate the cells so they will differentiate to form specific cell types, or inject the cells into an immunosuppressed mouse to test for the formation of a teratoma (a benign tumor containing a mixture of differentiated cells).

Stem Cell Cultures

Stem cells are either extracted from adult tissue or from a dividing zygote in a culture dish. Once extracted, scientists place the cells in a controlled culture that prohibits them from further specializing or differentiating but usually allows them to divide and replicate. The process of growing large numbers of embryonic stem cells has been easier than growing large numbers of adult stem cells, but progress is being made for both cell types.

About Our Stem Cell Center

Stem Cell Center of Modern Cancer Hospital Guangzhou mainly focus on clinical application study of stem cell therapy to treat various diseases. There are not only all kinds of stem cells which can be easily induced to generate various cell tissues, but also a unique extraction technology for autologous stem cells. Always with the rigorous scientific attitude, this center has been doing the purification, isolation and cultivation of stem cells in research labs through series of strict procedures. This process includes a series of pre-processings such as cells revival processing, stability processing, anti-rejection processing, adding inducer and in-vitro expansion, in order to guarantee the quality of cells and the curative effect of clinical transplantation.
