To investigate the effects of different concentrations of follicle-stimulating hormone (FSH) on the proliferation and apoptosis of human hemangioma stem cells, it will provide a basis for studying the mechanism of FSH in treating hemangioma.
Hemangioma specimens were collected from the Longgang District Maternity & Child Healthcare Hospital of Shenzhen City. Hemangioma stem cells were treated with different concentrations of FSH. Cell viability was detected by CCK8 method and cell apoptosis was analyzed by flow cytometry.
Hemangioma stem cells (HemSCs) were extracted from fresh tissue of infantile hemangioma by the CD133 immunomagnetic bead method. Under the influence of FSH at different concentrations (0, 100, 1000 IU/L), the cell viability of hemangioma stem cells increased significantly in a concentration-dependent manner ( < 0.05). At the same time, the apoptosis of hemangioma stem cells decreased with increasing concentrations of follicle-stimulating hormone ( < 0.05). Specifically, 1000 IU/L FSH significantly promoted the proliferation of hemangioma stem cells and inhibited their apoptosis.
High concentration of follicle-stimulating hormone can maintain the growth of hemangioma by promoting the proliferation and inhibiting the apoptosis of hemangioma stem cells.
探讨不同浓度促卵泡生成素(FSH)对人血管瘤干细胞增殖和凋亡的影响,为研究FSH治疗血管瘤的机制提供依据。
收集深圳市龙岗区妇幼保健院的血管瘤标本。用不同浓度的FSH处理血管瘤干细胞。采用CCK8法检测细胞活力,流式细胞术分析细胞凋亡情况。
采用CD133免疫磁珠法从婴幼儿血管瘤新鲜组织中提取血管瘤干细胞。在不同浓度(0、100、1000 IU/L)FSH作用下,血管瘤干细胞的细胞活力呈浓度依赖性显著增加(P<0.05)。同时,随着促卵泡生成素浓度的增加,血管瘤干细胞的凋亡减少(P<0.05)。具体而言,1000 IU/L FSH显著促进血管瘤干细胞的增殖并抑制其凋亡。
高浓度促卵泡生成素可通过促进血管瘤干细胞增殖、抑制其凋亡来维持血管瘤生长。
