EGFR hyperactivation increases sebaceous gland size and sebum production in mice.
research High proliferation and delamination during skin epidermal stratification
High proliferation and cell delamination drive early skin development, while later stages may not rely on cell division orientation.
research c-Myc activation in transgenic mouse epidermis results in mobilization of stem cells and differentiation of their progeny
c-Myc activation in mouse skin increases sebaceous gland growth and affects hair follicle development.

Ber‐EP4 marks cells related to the secondary hair germ in hair follicles.
research EGFR marks a subpopulation of dermal mesenchymal cells highly expressing IGF1 which enhances hair follicle regeneration.
A certain type of skin cell, marked by EGFR, produces a lot of IGF1 and helps hair follicles grow back faster.
research Epithelial elements in superficial angiomyxomas: mimicry of adnexal development, and mesenchymal‐to‐epithelial transition
Epithelial elements in superficial angiomyxomas are non-neoplastic growths mimicking embryogenesis.

Melanocyte precursors in human fetal skin follow a specific migration pattern and some remain in the skin's deeper layers.
research Genotoxic Agents: An Unexpected Effect on Healthy Epithelia
Chemotherapy drugs can cause abnormal growth and changes in healthy skin and gland cells.
research Seborrheic keratosis
Seborrheic keratosis is a common, harmless skin growth that can look like cancer, so it may need a biopsy.
