Kinetic Stem Cell Counting
All the Needed Applications
Asymmetrex®’s patented TORTOISE Test® and RABBIT Count® platforms provide essential applications for differentially quantifying and monitoring tissue stem cells.
TORTOISE Test®
For differentially quantifying tissue stem cells and monitoring their independent cell proliferation properties during culture expansion.
Tissue cell research
Improve research quality by knowing the differential number of critical tissue stem cells in experiments and delineating them from other cell types.
Cell Biomanufacturing and Supply
Monitor and optimize the expansion of tissue stem cells and the mature differentiated cells produced by their asymmetric division.
Rabbit Count®
For rapid determinations of the differential count of viable tissue stem cells present in cell-heterogeneous tissue cell preparations.
Stem cell medicine
Rapidly determine the accurate dosage of therapeutic tissue stem cells in stem cell and stem-gene therapy treatments based on a differential stem cell count.
Drug candidate evaluations
Determine if new drug candidates have positive effects on stem cells for healing or toxic effects that lead to drug failure.
The Impact of Accurate Differential Stem Cell Counting
The most significant impact of accurate differential stem cell counting will be the improvement of outcomes for patients receiving stem cell treatments and gene therapies that target tissue stem cells. Current treatments with inadequate stem cells result in avoidable increased morbidity for patients and their stem cell donors; and sometimes death for patients.
Accurate differential stem cell counting will also increase the quality of biomedical stem cell research, tissue and cell biomanufacturing (for both cell therapies and cultured food), and drug candidate evaluations, because all of these disciplines depend on the number and quality of tissue stem cells.
