Middle-aged skin shows aging signs, and quercetin might help delay them.

Pig skin cells can turn into mesodermal cells but lose their ability to become neural cells.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

Blood stem cells are diverse, influenced by many factors, and understanding them is key for progress in regenerative medicine.

Topical treatments can help improve beard growth.

Non-coding RNAs are important for hair growth and could lead to new hair loss treatments, but more research is needed.

Non-surgical procedures can help reduce wrinkles and stimulate skin repair by understanding skin aging at the molecular level.

Elastic Net DNA methylation clocks are inaccurate for predicting age and health status; a "noise barometer" may better indicate aging and disease.

Researchers found genes that control hair color and growth change before the visible coat color changes in snowshoe hares.

Immune cells in Hidradenitis suppurativa become more inflammatory and may be important for treatment targets.

Activating Nrf2 can help protect against hearing loss.

MicroRNAs are crucial in controlling cell signaling, affecting cancer and tissue regeneration.

Different types of fibroblasts play various roles in both healthy and diseased tissues, and understanding them better could improve treatments for fibrotic diseases.

Transplanting growing hair follicles into scars can help regenerate and improve scar tissue.

Lactate production is important for activating hair growth stem cells.

The article concludes that better understanding gene regulation related to seasonal changes can offer insights into the mechanisms of seasonal timing in mammals.

The p53 protein has complex, sometimes contradictory functions, including tumor suppression and promoting cell survival.

ROXY proteins help plants respond to nitrate shortage by affecting nutrient sensing and growth.

Food deprivation increases MST enzyme in the brain, possibly affecting energy balance.

Researchers identified specific genes that are important for mouse skin cell development and healing.

The research identified two types of keratinocytes in chicken scales: one for hard scales and another for soft skin, with similarities to human skin differentiation.

Zebrafish larvae are used to study and find treatments for ear cell damage because they are easier to observe and test than mammals.

Wnt1/βcatenin signaling is crucial for heart repair after injury.

Hair loss and aging are caused by the breakdown of a key protein in hair stem cells.

Male and female bodies respond differently to stress, influenced by hormones and development stages, with implications for stress-related diseases.

Fungi-produced compounds can change plant root growth.

Pectin biosynthesis is essential for the growth of cotton fibers and Arabidopsis root hairs.

The WNT signaling pathway is important in many diseases and targeting it could offer new treatments.

Rhodococcus equi causes severe pneumonia in young foals, and effective vaccines are needed due to foals' weak immune responses.

Fetal wound healing changes with development, affecting inflammation and collagen, which may influence scarring.
