As people age, their hair follicles produce less pigment, leading to gray and white hair, due to factors like reduced enzyme activity and damage to melanocyte DNA.

Dying cells can help with faster healing and new hair growth by releasing a growth-promoting molecule.

The research explains how a human enzyme binds and processes its substrate, which could relate to its role in biological functions and hair loss.

This new method makes checking for female infertility less painful, less invasive, and doesn't use radiation.

Hair follicles are complex, dynamic mini-organs that help us understand cell growth, death, migration, and differentiation, as well as tissue regeneration and tumor biology.

Stem cell niches are crucial for regulating stem cell behavior and tissue health, and their decline can impact aging and cancer.

Aging changes sugar molecules on skin stem cells, which may affect their ability to repair skin.

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

Triptorelin helps evaluate hormone production in Sertoli-Leydig cell tumors.

HPV6/11 is often found in hair of men with anogenital warts, especially pubic hair, and can lead to recurrent warts.

The conclusion is that accurately replicating the complexity of the extracellular matrix in the lab is crucial for creating realistic human tissue models.

Papaya leaves have many health benefits and medicinal uses.

CD10 and CD34 levels change during hair development and different hair growth stages, which could be important for hair regeneration treatments.

The PEEK cage reduced pain more than the dynamic cervical implant, but the implant allowed slightly better movement after surgery.
