Understanding how baby skin heals without scars could help develop treatments for adults to heal wounds without leaving scars.

Softer hydrogels help wounds heal better with less scarring.

The composite sponge helps heal diabetic wounds by reducing inflammation and promoting new blood vessel growth.

Transplanted hair follicle stem cells can heal damaged rat intestines.

New injectable hydrogels with gelatin, metal, and tea polyphenols help heal diabetic wounds faster by controlling infection, improving blood vessel growth, and managing oxidative stress.

Modified rat stem cells on a special scaffold improved blood vessel formation and wound healing in skin substitutes.

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.

Selenium can be toxic to animals, causing serious health issues, especially in horses.

Activating TLR5 in the gut can extend lifespan and improve health in aged mice.

Pannexin 3 is important for bone formation and the development of bone cells.

High levels of ERK activity are key for tissue regeneration in spiny mice, and activating ERK can potentially redirect scar-forming healing towards regenerative healing in mammals.

The lentiviral array can monitor and predict gene activity during stem cell differentiation.

Some nutrients and antioxidants may improve skin and hair health, but more research is needed to confirm these benefits.

The skin microbiome helps heal wounds and can be targeted to improve healing.

Rapamycin treatment helps with mitochondrial disease by reducing PKC levels.

The dermal regeneration template is effective in skin regeneration, reducing scarring, and has potential for future improvements.

Microneedle arrays with nanotechnology show promise for painless drug delivery through the skin but need more research on safety and effectiveness.

FGF9 controls which receptors it binds to through a process where two FGF9 molecules join, and changes in FGF9 can lead to incorrect receptor activation.

Mechanical forces are crucial for shaping cells and forming tissues during development.

The conclusion is that Treg-targeted therapies have potential, but more knowledge of Treg biology is needed for effective treatments, including for cancer.

Modern wound dressings like hydrocolloids, alginates, and hydrogels improve healing and are cost-effective.

The gene Tfap2b is essential for creating a type of stem cell in zebrafish that can become different pigment cells.

HDAC6 helps keep ovarian follicles dormant, extending female fertility.

The research showed how melanocytes develop, move, and respond to UV light, and their stem cells' role in hair color and skin cancer risk.

Carbon dots show promise for tissue repair and growth but need more research to solve current challenges.

A new mRNA variant of the SCF gene in sheep skin produces a shorter, different protein.

Paclitaxel is an effective cancer drug with side effects and potential new uses beyond cancer.

Inorganic-based biomaterials can quickly stop bleeding and help wounds heal, but they may cause issues like sharp ion release and pH changes.

Some small molecule antivirals show promise against COVID-19, but more research is needed to understand and improve them.

Understanding where cancer cells come from helps create better prevention and treatment methods.
