Micro-Morphometric Study of Skin in Developing Human Fetuses and Its Clinical Relevance

The study examined the microanatomy of fetal skin development from 8 to 30 weeks of gestation using histological methods on 24 human fetuses. It found that epidermal differentiation began at 8 weeks, hair follicles appeared at 16 weeks, and eccrine sweat glands at 20 weeks. The research highlighted that fetal age could be determined by skin features and that understanding normal fetal skin development could help predict congenital skin diseases. Fetal skin's unique ability to heal without scarring was noted. The study concluded that recognizing distinct patterns in skin development was crucial for diagnosing congenital skin diseases like restrictive dermopathy, ectodermal dysplasia, and epidermolysis bullosa, emphasizing the clinical relevance of understanding fetal skin morphology.
