The reticulin fibers were mainly derived from CAFs in AML. Microphotographs displaying IHC staining for Vimentin, FSP1, α-SMA, FAP and CD68 in the BM sections of the normal controls and primary AML patients. Both images are at a magnification of 400×. The horizontal bar below the images indicates the percentage of positive cells that expressed Vimentin, FSP1, α-SMA, FAP and CD68 in the BM sections between these two groups (n = 3),** p < 0.01
