Precursor (Progenitor) Stem Cells
Precursor (progenitor) stem cells are specialized stem cells that, after the stage of organogenesis, are committed to developing into specific types of cells within their tissue of origin. They divide and differentiate into specialized cells, directly replacing malfunctioning or damaged cells in the body caused by injury or disease. This process is guided by specific signals that direct the cells along a predetermined path. The therapeutic use of these stem cells has been supported by extensive research, demonstrating their safety and potential in treating various medical conditions.
What is Precursor Stem Cell?
Precursor stem cells utilize primary organ culture tissue fragments and/or cell clusters derived from New Zealand white rabbits, ensuring that the cells maintain a diploid set of chromosomes characteristic of normal somatic cells and the animal's organ cultures. These primary tissue cultures are sourced from an E.U.-certified closed colony, which has been maintained for at least 30 generations since 1973. The cells are extracted with others from the same "family" in close cell-to-cell contact, including various generations within the same lineage. These cells are then placed into a primary tissue culture for observation and safety testing. This process is designed to eliminate immunogenicity, reducing the need for immunosuppressant drugs.
