Study Notes
Primary Uses of Stem Cells
- Mainly used for regenerative medicine and tissue repair.
- Critical for understanding development and disease pathology.
Differentiation Stimulation
- Stem cells are stimulated to differentiate through specific growth factors or signaling molecules.
- Conditions such as temperature, oxygen levels, and substrate can also influence differentiation.
Cell Re-plating Process
- When culture dishes become crowded due to cell division, the process is referred to as "passaging" or "subculturing."
- Re-plating is essential to maintain healthy cell growth and prevent over-confluence.
Transport of Stem Cells
- Batches of stem cells are typically transported in controlled temperature conditions to ensure viability.
- Specialized packaging materials are used to protect cells during transit, avoiding physical damage.
Stem Cell Therapy Method
- Stem cell therapy often employs autologous stem cells, meaning they are derived from the patient’s own tissue.
- Immunosuppression may be required to prevent rejection of transplanted cells.
Most Important Source for Tissue Regeneration
- Induced pluripotent stem cells (iPSCs) have emerged as a significant source due to their ability to differentiate into any cell type.
- Adult stem cells, such as those from bone marrow and adipose tissue, are also critical for therapies.
