Testosterone can help premenopausal and postmenopausal women with low sexual desire, but its long-term safety is unclear and it's not widely approved for this use.

Leptin-deficient mice, used as a model for Type 2 Diabetes, have delayed wound healing due to impaired contraction and other dysfunctional cellular responses.

Tiny particles called extracellular vesicles show promise for treating skin conditions and promoting hair growth.

Chitosan hydrogels are promising for repairing blood vessels but need improvements in strength and compatibility.

Stem cells and their exosomes show promise for repairing tissues and healing wounds when delivered effectively, but more research is needed on their tracking and optimal use.

Turning off a specific gene in stem cells speeds up skin healing by helping cells move better.

The secretome from mesenchymal stromal cells shows promise for improving facial nerve injury treatment.

The document outlines steps for moving fat from one body part to another.

Hydrogels combined with extracellular vesicles and 3D bioprinting improve wound healing.

The Msx2 gene affects feather development in Hungarian white geese and a specific gene variation could indicate feather quality.

Activating TLR9 helps heal wounds and regrow hair by using specific immune cells.

Biopolymers are increasingly used in cosmetics for their non-toxicity and skin benefits, with future biotech advancements likely to expand their applications.

Bead-jet printing of stem cells improves muscle and hair regeneration.

Phytotherapeutic compounds and supplements can help manage Polycystic Ovarian Syndrome (PCOS).

Two siblings had a rare immune disorder caused by a FOXN1 gene mutation.

A newborn girl has a rare skin condition with two ulcers on her buttock that are healing on their own.

Skin patterns form through molecular signals and genetic factors, affecting healing and dermatology.

Human dermal stem cells can become functional skin pigment cells.

The gene Prss53 affects hair shape and bone development in rabbits.

Noggin is necessary to start the hair growth phase in skin after birth.

Wnt1a-conditioned medium from stem cells helps activate cells important for hair growth and can promote hair regrowth.

The environment around melanocyte stem cells is key for hair regeneration and color, with certain injuries affecting hair color and potential treatments for pigmentation disorders.

The conclusion is that skin and hair patterns are formed by a mix of cell activities, molecular signals, and environmental factors.

A man had an allergic reaction to minoxidil, which stopped after he discontinued use and started corticosteroids.

A woman developed a cyst in her parotid gland after a botox injection, which was successfully removed with surgery.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

Feather patterns form through genetic and epigenetic controls, with cells self-organizing into periodic patterns.

Malt1 protease is essential for regulatory T cell function and could be targeted to boost antitumor immunity.

Human skin can provide stem cells for tissue repair and regeneration, but there are challenges in obtaining and growing these cells safely.

The research found ways to activate melanocyte stem cells for potential treatment of skin depigmentation conditions.
