概括

水溶性重组基氨酸 (RKs) 通过增强毛囊活动来促进头发生长. RK81显著改善了头发的直径和质量,提供了一个新的治疗途径.

科学领域:

生物化学生物化学
皮肤病学皮肤病学
生物材料科学生物材料科学

背景情况:

质素是头发的关键营养素,但提取物是复杂的,纯重组质素的溶解性较差,限制了它们的头发生长应用.
由于纯重组形式的提取复杂性和可溶性问题,研究质素对头发生长的机制具有挑战性.

研究的目的:

为增强头发生长研究设计水溶性重组质 (RKs).
调查新型水溶性RKs在促进毛囊 (HF) 活动和头发再生方面的有效性.
为了比较RK81和RK31促进头发生长的作用及其作用机制.

主要方法:

使用QTY代码方法理性设计可溶于水的重组基氨酸 (RKs) K31和K81.
使用用于局部输送的设计RK制造微针.
评估毛囊异质进入,新头发直径和HF活动.
对PI3K/AKT/Nf-κB信号通路升调的分析.

主要成果:

与RK31.31相比,RK81显著促进了HF的异原体进入 (到第12天超过40%),并增加了新的头发直径 (15.10 ± 2.45μm).
与传统的角质提取物和氧化相比,水溶性RKs显示出HF活性和头发再生的优异增强.
观察到PI3K/AKT/Nf-κB信号轴的升调,这表明增强头发生长的关键机制.

结论:

设计的水溶性重组基氨酸,特别是RK81,显示出促进头发生长和改善头发质量的巨大潜力.
通过QTY代码的方法,可以创建具有增强治疗疗效的可溶性重组蛋白质,用于头发再生.
这项研究为开发针对脱发和改善头发健康的基于质素的先进疗法开辟了新的可能性.

Multipotency and Niche of Bulge Stem Cell

Multipotency and Niche of Bulge Stem Cell

A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...

Renewal of Skin Epidermal Stem Cells

Renewal of Skin Epidermal Stem Cells

The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular...
