UPDATED September 04, 2020 – The iliac crest is a prominent thick curved bone located in the upper border of the ilium near the pelvis. The iliac crest gets its name from it concave shape, that rounds inward, convex in back area and rounding outward. The iliac crest is that stretch of space posteriorly running from the anterior superior iliac spine (ASIS) towards the posterior superior iliac spine (PSIS) which is a source for somatic stem cells.
It is known to contain a huge supply of bone marrow, which accounts for its being an uncommon extraction site for protocols at the stem cell regeneration center of Thailand treatment center and are typically only used in rare cases that required previous transplantation of bone marrow stem cells.
