Stem Cell Viability

Stem cells are undifferentiated primitive cells with multilineage differentiation potential and self-renewal ability. Under certain conditions, stem cells can differentiate into functional cells. Stem cells are either elliptical or round in shape.

Stem cell therapy refers to the transplanting of healthy stem cells into the patient’s body to treat diseased cells or reconstruct normal cells and tissues. The research into stem cells is one of the hottest medical and scientific research topics.

1、Embryonic stem cells (ES): embryonic stem cells are stem cells derived from early embryo (earlier than gastrula stage) or primary gonads, and characterized by in vitro culture, infinite proliferation, self-renewal and multilineage differentiation.

2、Bone marrow stem cells (extracted from tissue): bone marrow samples contain a large number of stem cells and also large numbers of red blood cells (RBCs) and platelets. Generally, labs which need to count bone marrow stem cells have to do a lot of work, and it is difficult and laborious to count such cells and evaluate their viability. Countstar can accurately analyze the concentration and viability of bone marrow stem cells after the red blood cells in the sample have been removed. The measurements of Countstar® are shown in the following figure:

4、Spermatogonial stem cells (SSCs): SSCs are cells which can differentiate into sperms. In the scientific research, SSCs are one of the most common cells in development biology and reproductive biology research.
