The symposium concluded that understanding how different species repair tissue and how this changes with age can help advance regenerative medicine.

In vivo lineage labelling is better than in vitro methods for identifying and understanding stem cells.

Growth hormone levels affect hair growth and loss, with too much causing excess hair and too little leading to hair loss.

Melanocytes are important for normal body functions and have potential uses in regenerative medicine and disease treatment.

Estrogens significantly influence hair growth by interacting with receptors in hair follicles and may help regulate the hair growth cycle.

Melasma's causes include genetics, sun exposure, hormones, and oxidative stress, and understanding these can help create better treatments.

Environmental factors at different levels control hair stem cell activity, which could lead to new hair growth and alopecia treatments.

New antiscarring strategies show promise, including drugs, stem cells, and improved surgical techniques.

Lymphocytes, especially CD8+ T cells, play a key role in causing alopecia areata, and targeting them may lead to new treatments.

Animal models have helped understand hair loss from alopecia areata and find new treatments.

Probiotics show promise for health benefits but need more research to understand how they work.

Alopecia areata involves complex immune and genetic factors, with potential treatment targets identified, but more research is needed.

Scalp cooling can help prevent chemotherapy-induced hair loss with a 50-90% success rate and is safe for patients.

Hair loss due to scalp metastasis from breast cancer, known as Neoplastic Alopecia, has a better survival rate than other scalp metastases and requires a biopsy for diagnosis.

The sebaceous gland has more roles than just producing sebum and contributing to acne, and new research could lead to better skin disease treatments.

Bone-marrow and epidermal stem cells help heal wounds differently, with bone-marrow cells aiding in blood vessel formation and epidermal cells in hair growth.

Hair follicles prevent NK cell attacks to avoid hair loss.

Skin bacteria, specifically Streptococcus and Staphylococcus, help in hair regrowth after skin injury and speed up wound healing.

We need better treatments for hair loss, and while test-tube methods are helpful, they can't fully replace animal tests for evaluating new hair growth treatments.

Hair follicle stem cells are key for hair and skin regeneration, can be reprogrammed, and have potential therapeutic uses, but also carry a risk of cancer.

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.

High levels of male hormones, insulin resistance, and obesity are closely linked and worsen polycystic ovary syndrome, but more research is needed to improve treatments.

Cicatricial alopecia, a permanent hair loss condition, is mainly caused by damage to specific hair follicle stem cells and abnormal immune responses, with gene regulator PPAR-y and lipid metabolism disorders playing significant roles.

Magnesium Silicate Sprays help heal burn wounds and regrow skin features better than commercial products.

Male pattern baldness may be caused by scalp pressure on hair follicles, which increases with age and leads to a cycle of hair loss. This process is not directly determined by genes.

Hair ages due to genetics and environmental factors, leading to graying and thinning, with treatments available for some conditions.

Ovol2 is crucial for hair growth and skin healing by controlling cell movement and growth.

Laser therapy might help regrow hair in alopecia totalis better than steroids alone.

The niche environment controls stem cell behavior and plasticity, which is important for tissue health and repair.
