Web29 okt. 2016 · However, SOX9, SOX18, and SOX5 have also been implicated in regulating aspects of the melanocyte life cycle. SOX9 (a nuclear stain), and SOX10 (a perinuclear and cytoplasmic stain) have been reported to be expressed in various stages of melanoma progression and in established melanoma cell lines [ 37 – 39 ]. Web4 feb. 2005 · In addition, Bcl2 –/– follicles in the second hair cycle lack both differentiated melanocytes in the hair bulb and undifferentiated Dct-lacZ + melanoblasts in the stem-cell niche (located at the bulge area in pelage follicles) (Fig. 1, D and E, and fig. S2, i and j), suggesting that Bcl2 might be important for survival of melanocyte stem cells.

Web3 mei 2024 · As old hairs fall out and new hairs grow in, melanocyte stem cells serve as a reservoir for the melanocytes that produce the pigment that gives hair its visible color. The loss of these stem cells leads to the growth of nonpigmented, or gray, hairs. Evaluating mouse models of hair graying can reveal key aspects of melanocyte stem cell biology. WebAfter this time, melanocyte-specific autoantibodies appear again in the peripheral circulation 1-2 weeks before the onset of SLV. However, the contribution of these autoantibodies to the onset and progression of SLV has not been defined.
