Abstract

Hair regenerative medicine is a promising approach for the treatment of hair loss and involves the transplantation of follicular stem cells into bald spots to regenerate hair. Various approaches have been investigated to engineer tissue grafts for use in hair regenerative medicine. Tissue-like three-dimensional aggregates, such as bioengineered hair follicle germs (HFGs), have shown great promise for hair regeneration, with normal tissue morphology and hair cycles. However, these approaches have not yet been applied in clinical settings, and further studies are needed to improve hair generation efficiency. The biological molecules in in vivo microenvironments around HFGs may provide cues for the in vitro preparation of HFGs with higher trichogenic functionalities. Activated platelet-rich plasma releasate (PRPr) is an autologous source of signaling molecules including growth factors and cytokines. In this study, we investigated the effects of PRPr on the preparation of HFGs in vitro. The presence of PRPr did not hinder the spontaneous formation of dumbbell-like HFGs from a suspension of embryonic skin-derived epithelial and mesenchymal cells in a custom-designed HFG culture plate. HFGs prepared with PRPr displayed greater levels of follicular gene expression compared to those prepared in the absence of PRPr. Moreover, the hair regeneration ability upon intracutaneous transplantation was significantly improved in the presence of PRPr. These results suggest that PRPr is beneficial for engineering HFGs for autologous hair regenerative medicine.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
