research DKK1 Mediated Inhibition of Wnt Signaling in Postnatal Mice Leads to Loss of TEC Progenitors and Thymic Degeneration
Blocking Wnt signaling in young mice causes thymus shrinkage and cell loss, but recovery is possible when the block is removed.
research Promotion of homology-directed DNA repair by polyamines
Polyamines help fix DNA damage accurately in cells.
research Melatonin promotes secondary hair follicle development of early postnatal cashmere goat and improves cashmere quantity and quality by enhancing antioxidant capacity and suppressing apoptosis
Melatonin improves cashmere goat hair growth and quality by increasing antioxidants and reducing cell death.
research Transient mitochondrial DNA double strand breaks in mice cause accelerated aging phenotypes in a ROS-dependent but p53/p21-independent manner
Damaging mitochondrial DNA in mice speeds up aging due to increased reactive oxygen species, not through the p53/p21 pathway.
research Proliferation, but Not Apoptosis, Is Associated with Distinct β-Catenin Expression Patterns in Non-Small-Cell Lung Carcinomas
Distinct β-catenin patterns are linked to cell growth, not cell death, in lung cancer.
research Isolation of epithelial stem cells from dermis by a three-dimensional culture system
Researchers isolated a new type of stem cell from mouse skin that can renew itself and turn into multiple cell types.

research The Phytocannabinoid (–)-Cannabidiol Operates as a Complex, Differential Modulator of Human Hair Growth: Anti-Inflammatory Submicromolar versus Hair Growth Inhibitory Micromolar Effects
CBD can either reduce inflammation and not affect hair growth at low levels or inhibit hair growth at high levels.
research Panax ginseng extract antagonizes the effect of DKK-1-induced catagen-ike changes of hair follicles
Panax ginseng extract may help prevent hair loss caused by DKK-1.
research iRhom2 Mutation Leads to Aberrant Hair Follicle Differentiation in Mice
A mutation in the iRhom2 gene causes hairless mice due to abnormal hair follicle development.
research Brain-targeted intranasal delivery of protein-based gene therapy for treatment of ischemic stroke
Intranasal delivery of gene therapy shows promise for treating ischemic stroke.
research Hair follicle mesenchymal stem cell exosomal lncRNA H19 inhibited NLRP3 pyroptosis to promote diabetic mouse skin wound healing
A substance from hair follicle stem cells helps heal skin wounds in diabetic mice by promoting cell growth and preventing cell death.
research Protective effects of human umbilical cord blood‑derived mesenchymal stem cells against dexamethasone‑induced apoptotic cell death in hair follicles
Stem cells from umbilical cord blood may prevent hair loss caused by certain medications.
research Hair regenerative effect of silk fibroin hydrogel with incorporation of FGF-2-liposome and its potential mechanism in mice with testosterone-induced alopecia areata
The silk fibroin hydrogel with FGF-2-liposome can potentially treat hair loss in mice.
