Thus, a mean of 2.81 ± 1.18 CD163-positive BMGCs/mm2 were found in the group of the pure BBS, while in the group of the BBS combined with the low concentration of HY it was 2.31 ± 1.47 CD163-positive BMCGs/mm2 and in the group of the BBS combined with the high concentration of HY 3.59 ± 2.06 CD163-positive BMGCs/mm2 were measured (Figure 4). Here, CD163 is linked to Bardet-Biedl syndrome.
