November 2020 in “bioRxiv (Cold Spring Harbor Laboratory)” This study in live mice suggests that hair follicle regression involves apoptosis propagation towards stem cells, potentially slowed by a protective signal from the stem cells themselves.

January 2017 in “Dermatologic Surgery” This study observed that storing hair follicle micrografts significantly decreased the expression of certain key genes in the dermal papilla, potentially affecting hair follicle cycling during preparation and storage.

June 2015 in “Nature Protocols” This protocol describes using two-photon laser-scanning microscopy to study hair regeneration in live mice, offering detailed imaging capabilities for observing hair follicle stem cell behavior and manipulating cellular populations.
October 2023 in “Oncotarget” In this study using live mice, researchers observed that during hair follicle regression, apoptosis in basal cells may propagate by triggering neighboring cells, potentially regulated by a gradient of pro-survival signals from stem cells, and proposed a testable mechanism to further explore this process.
January 2005 in “Вестник Оренбургского государственного университета” This study found that minoxidil combined with all-trans retinoic acid additively promoted hair growth in vitro by enhancing cell survival and reducing apoptosis compared to minoxidil alone.
