CD8A and hydrops fetalis: Here, we provide a description of changes in cell numbers of fibroblasts, HF dermal papilla, endothelial cells, keratinocytes (interfollicular epidermis, HF-infundibulum, HF-isthmus, HF-bulge (basal and suprabasal), HF-hair germ) and immune cells (macrophages, monocytes, dendritic cells, T cells (CD4+, CD8+, CD4+/CD8+, regulatory T cells) and neutrophils) based on flow cytometric analysis.
