Establishing Competent Morphogenetic Fields for Tissue Pattern Regeneration in Skin Organoids

This study found that engineered reconstituted skin can form morphogenetic units that promote tissue patterning and hair regeneration, with certain signaling pathways restoring this ability in adult and fetal cells.

This study found that carefully engineered hydrogels and asymmetric morphogen gradients facilitated the formation of anatomically relevant skin organoids from iPSC-derived EBs, improving pigmentation and hair follicle generation.

This study demonstrated that hiPSC-derived hair-bearing skin organoids lacked sufficient type VII collagen at the epidermal-dermal junction, indicating a need for further maturation to model certain forms of epidermolysis bullosa effectively.

This study introduced a bioengineering platform that creates early-stage hair peg-like structures within tissue-engineered skin substitutes by integrating human keratinocytes and dermal papilla cells with laser-micropatterned collagen scaffolds, providing a foundation for future appendage-inclusive skin regeneration efforts.

This paper discusses the multipotency of cyst cells and proposes that understanding molecular circuits in cyst formation could enable engineering of desired stem cell culture phenotypes, but reports no new experimental outcomes.
