Up to now, the pathogenesis of vitiligo remains obscure, such as the genetic, autoimmune, neural, and melanocyte self-destruction hypotheses.
迄今为止,白癜风的发病机制尚不完全清楚,有遗传学说、自身免疫学说、神经学说和黑素细胞自毁学说等。
The tanning process occurs within the epidermis when melanocyte cells are stimulated by ultraviolet light that causes them to produce the pigment melanin.
而受到照射的过程中,黑素细胞受到紫外线照射的刺激,产生出黑色素。
Results: Anchoring cells were mostly amelanotic melanocyte in early stage, only a small quantity of keratinocyte and none of fibroblast.
结果培养物中初始贴壁细胞大多数为无色素黑素细胞,仅有少量的角质形成细胞,无成纤维细胞污染。
Objective: To develop a compound staining method showing collagenic, elastic fibers and melanocyte in skin tissues.
目的:寻找能显示皮肤组织黑素细胞与胶原纤维和弹力纤维的染色法。
A dark-pigmented, usually malignant tumor arising from a melanocyte and occurring most commonly in the skin.
黑瘤,黑素瘤含有黑色素的,通常为恶性的肿瘤,由黑素细胞引起且最常见于皮肤中。
DNA damage was detected in all melanocyte cells and these cells were unable to repair the damage.
结果发现在所有黑色素细胞中均可检出DNA损伤,而且这些细胞不能够对损伤进行修复。
Conclusion There are anti-MCHR1 antibodies in sera of some patients with vitiligo. MCHR1 is one of vitiligo related antigen and it is located on melanocyte membrane.
结论白癜风患者血清中存在抗mchr1的自身抗体,MCHR1是MC膜表面的白癜风相关抗原。
Then, the content of melanin in antisense TRP-1 transfected melanocyte was detected.
测定TRP - 1反义核酸转染黑素细胞后细胞内黑素含量的变化。
DopA is the most suitable method to observe the quantity of melanocyte and melanin granules.
多巴氧化酶法在几种方法中是最适合观察黑色素细胞数量和黑色素颗粒的方法。
Scientists found that such melanocyte stem cells lacked a crucial enzyme that was present in similar stem cells found in the skin, which do not lose colour with age.
科学家发现这种黑素细胞干细胞缺少一种至关重要的酶,这种酶存在于在皮肤里发现的类似的干细胞里,而皮肤不随着年龄褪色。
Conclusion as a specific antigen in mixed melanocyte lymphocyte reaction, melanocyte has a weak effect on the lymphocytes.
结论正常人黑素细胞的促淋巴细胞转化增殖的特异性抗原作用较弱。
Expression of NOS was assayed with immunohistochemical method and melanocyte was identified under high-times optic microscope to observe stain and characteristic of cytoplasm.
免疫组织化学方法法显示一氧化氮合酶的表达,用光学显微镜在高倍镜下观察,识别黑素细胞,观察细胞胞质的染色及特点。
Conclusion ET-1 is more effective in enhancing melanocyte adhesion and migration than SCF.
结论ET 1可以促进黑素细胞的黏附和迁移,其效果优于scf。
The rapid proliferation and increased dendrites of melanocytes in 254 media supplemented with human melanocyte growth supplement (HMGS) were observed.
采用添加人黑素细胞生长成分(HMGS)的254培养基,细胞增殖快,黑素细胞树突数目和分级增多。
