CD34 and metabolic dysfunction-associated steatotic liver disease: The results showed that B-cell, fibroblasts, Pro-B cell CD34+, GMP, and BM components were significantly higher in NAFLD than healthy liver, while the endothelial cells, monocytes, and tissue stem cells were lower, suggesting that the occurrence of NAFLD led to the component increase of fibroblasts and BM, while the decrease of endothelial cells and tissue stem cells.
