Stem cells help repair tissue mainly by releasing beneficial substances, not by replacing damaged cells.

The congress highlighted new gene therapy techniques and cell transplantation methods for treating diseases.

Exosomes could potentially enhance tissue repair and regeneration with lower rejection risk and easier production than live cell therapies.

Electrospun nanofibers show promise for enhancing blood vessel growth in tissue engineering but need further research to improve their effectiveness.

Stem cell-derived conditioned medium shows promise for treating various medical conditions but requires standardized production and further validation.

Umbilical cord blood is a valuable source of stem cells for medical treatments, but its use is less common than other transplants, and there are ethical issues to consider.

Tiny particles from brain cells help hair grow by targeting a specific hair growth pathway.

Lipocalin-Type Prostaglandin D2 Synthase (L-PGDS) is a protein that plays many roles in the body, including sleep regulation, pain management, food intake, and protection against harmful substances. It also affects fat metabolism, glucose intolerance, cell maturation, and is involved in various diseases like diabetes, cancer, and arthritis. It can influence sex organ development and embryonic cell differentiation, and its levels can be used as a diagnostic marker for certain conditions.

miRNA-based therapies show promise for treating skin diseases, including hair loss, in animals.

Exosomes may improve skin, scars, hair growth, and fat grafts in plastic surgery, but more research is needed.

The review concludes that innovations in regenerative medicine, tissue engineering, and developmental biology are essential for effective tissue repair and organ transplants.

Stem cell niches support, regulate, and coordinate stem cell functions.
