概括

皮肤发育涉及相互依存的组织,如脂肪,肌肉和血管系统. 鸟类皮肤表现出两种不同的脂肪生成波,SWAT和DWAT,适应环境需求,特别是在子中.

科学领域:

发育生物学是发展生物学.
比较解剖学的比较解剖学.
组织工程是组织工程.

背景情况:

皮肤架构平衡了相似性和多样性,但其发育组合的理解很少.
以前的研究表明,皮内肌肉和血管系统在皮的羽毛芽周围组织起来.
鸟类皮肤包含皮下白色脂肪组织 (SWAT) 和皮肤白色脂肪组织 (DWAT).

研究的目的:

研究鸟类脂肪组织的发育,并将其与物种 (,长,) 进行比较.
探索皮肤白色脂肪组织 (DWAT) 和皮肤光滑肌肉之间的关系.
检查根据环境因素对脂肪组织发育的适应性差异.

主要方法:

使用弹性质染色来区分皮肤和皮下层.
采用Oil Red O染色来可视化脂肪生成波.
使用SMA-Cre进行血统追踪,并与C/EBPα抗体共同染色.

主要成果:

确定了两种不同的脂肪生成波:SWAT (约E14) 与血管系统保持一致,DWAT (约E16) 与光滑肌肉形成网格模式.
证明了SMA阳性细胞和脂肪细胞之间的潜在共享血统,SMA+细胞产生脂肪细胞.
与相比,在子中观察到明显更多的SWAT和DWAT,这表明了适应.

结论:

鸟类皮肤的发育涉及相互依存的组织组成部分,包括羽毛,脂肪,血管和皮肤光滑肌肉.
这些相互关联的发展关系是适应性的,允许物种适应它们的环境.
这些发现为研究皮肤可塑性的调节机制奠定了基础.

Hypodermis

Hypodermis

The hypodermis (the subcutaneous layer or superficial fascia) is present directly below the dermis. It connects the skin to the underlying fascia (fibrous tissue) of the bones and muscles. It is not strictly a part of the skin, although the border between the hypodermis and dermis can be difficult to distinguish. The hypodermis consists of well-vascularized, loose, areolar connective tissue and adipose tissue, which functions as a mode of fat storage and provides insulation and cushioning for...

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...
