March 2022 in “Nature Protocols” Researchers have developed a protocol to generate hair-bearing skin tissue from human pluripotent stem cells in a 3D in vitro culture system. Over 2 weeks, these stem cells differentiate into surface ectoderm and cranial neural crest cells, forming the epidermis and dermis. After 60 days, hair follicles appear, and by 130 days, the organoids exhibit full complexity, including stratified skin layers, pigmented hair follicles, sebaceous glands, Merkel cells, and sensory neurons, mimicking fetal skin at 18 weeks of gestation. These organoids can be cultured for up to 150 days, offering a model for studying skin biology, disease, and potential skin tissue regeneration.
June 2023 in “Frontiers in Bioengineering and Biotechnology” The conclusion is that accurately replicating the complexity of the extracellular matrix in the lab is crucial for creating realistic human tissue models.
