WHERE can you find HSCs?

Red Bone Marrow
Liver
Spleen
Umbilical Cord Blood
Placenta
  • HSCs are found in the red bone marrow of adults, and a small number of them are found in spleen and liver.

  • They are also found in umbilical cord blood and placenta.

  • A stem cell niche is where the stem cells reside, and it is a stable environment for stem cells.

  • Regulation of HSC function relies on specialized cells and factors in the HSC niches.

  • The condition of the niches is related to stem cell diseases.
