561-哺乳动物皮肤表皮钉突的进化与发育机制

这项研究揭示了表皮突（rete ridges）作为一种独特的哺乳动物皮肤附属器官的演化与发育机制。通过对人类、猪和海豚等多种动物进行比对，科学家发现表皮突的形成与毛发密度减少及皮肤增厚密切相关，旨在提供结构支撑和防御优势。不同于在胚胎期发育的毛囊或汗腺，表皮突是在出生前后通过独特的分子路径产生的。研究强调，BMP信号通路的广泛激活是驱动表皮突网络形成的核心要素，而传统的WNT信号在此过程中则处于失活状态。这些发现不仅解开了人类演化中皮肤结构改变的谜团，还为通过再生皮肤附属结构来治疗伤口愈合和皮肤老化提供了新的临床思路。References:* Thompson S M, Yaple V S, Searle G H, et al.
