Lizards can regrow their tail scales with the same structure, distribution, and gender-specific features as the original ones, and this unique ability is not seen in adult mammals.

Manatee whiskers are specially adapted for touch in water.

Adult mesenchymal stem cells can help regenerate tissues and are promising for healing bones, wounds, and hair follicles.

Androgens can cause hair growth in some areas and hair loss on the scalp.

The document concludes that while some organisms can regenerate body parts, mammals generally cannot, and cancer progression is complex, involving mutations rather than a strict stem cell hierarchy.

The study concluded that tick infestation was the most common skin problem in hospitalized dogs in Chennai, with various treatments used for different conditions.

Understanding fetal skin development helps diagnose congenital skin diseases.

Hair in mammals likely evolved from glandular structures, not scales.

Different whale and dolphin species have unique whisker follicle structures, suggesting they might use their whiskers in various ways.

Licorice has many traditional health benefits, but more research is needed to fully support these claims.

The document suggests creating a secure database for indigenous knowledge and recommends that the TKDL actively fight patents that slightly alter traditional knowledge.

Keratinocytes and adipose-derived stem cells can effectively heal difficult skin wounds.

Different body areas in mice produce different hair types due to interactions between skin layers.

Testosterone is key for male sexual function, and treating hormone imbalances can improve sexual issues.

The document concludes that understanding the evolution of the human face helps cosmetic surgeons meet aesthetic desires.

Ayurveda can help treat premature hair graying with lifestyle changes and herbal remedies.

The skin systems of jawed vertebrates evolved diverse appendages like hair and scales from a common structure over 420 million years ago.

Humans have limited regenerative abilities, but new evidence shows the adult brain and heart can regenerate, and future treatments may improve this by mimicking stem cell environments.

Glycine slows main root growth but boosts root hair growth in habanero peppers.

Dynamic, light touch is sensed through a common mechanism involving Piezo2 channels in sensory axons.

Mice without the Sp6 gene have problems developing several body parts, including hair, teeth, limbs, and lungs.

The skin's layers protect, sense, and regulate the body's internal balance, but can be prone to cancer.

Ectodin integrates BMP, SHH, and FGF signals in developing ectodermal organs.

SARS-CoV-2, the virus causing COVID-19, can affect all endocrine organs and systems, altering their function and potentially leading to disorders. Factors like diabetes and obesity increase infection risk and severity. Understanding these effects is key for effective treatment.

Ellis van Creveld syndrome, a rare genetic disorder, can cause unexpected abnormalities in various body organs, requiring thorough patient evaluations.

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.

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

Mechanical force is important for the first contact between skin cells and hair growth in mini-organs.

Skin has specialized touch receptors that can tell different sensations apart.

Regenerative pharmacology, which combines drugs with regenerative medicine, shows promise for repairing damaged body parts and needs more interdisciplinary research.
