Fetal integumentary histology
- At 14 weeks, the epidermis consisted of a basal layer, an intermediate cell layer and periderm.
- At 20 weeks, the number of intermediate cells layers was increased and developing hair follicles were visible.
- The adult skin contained basal, spinous, granular and cornified layers.
This study gestational ages were estimated by menstrual age and ranged from 13 to 22 weeks. The embryo gestational ages and numbers were as follows: gestational age 13 weeks (1), 14 weeks (1), 16 weeks (1), 17 weeks (2), 18 weeks (2), 19 weeks (4), 20 weeks (4), 21 weeks (3), 22 weeks (3).
