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.
