Did you mean Reticular Fibroblasts?

Glossary Reticular Fibroblasts

Reticular fibroblasts are specialized cells found in the connective tissue that play a crucial role in the formation of the extracellular matrix, particularly in lymphoid organs. In the context of hair loss, these fibroblasts contribute to the structural integrity of the dermal papilla and surrounding tissues, which are essential for hair follicle development and cycling. Key distinguishing characteristics include their ability to produce collagen and other matrix components, influencing the overall health and function of hair follicles. Dysfunction or alterations in reticular fibroblasts can lead to impaired hair growth and contribute to various forms of hair loss.

research RANKL Induces Organized Lymph Node Growth by Stromal Cell Proliferation

42 citations , December 2011 in “The journal of immunology/The Journal of immunology”

In this study, transgenic mice with Rank expression in hair follicles showed excessive lymph node growth, which could be normalized by neutralizing the overproduced RANKL, underscoring its role in immune system regulation.

research Distinct Fibroblast Lineages Give Rise to NG2+ Pericyte Populations in Mouse Skin Development and Repair

37 citations , May 2021 in “Frontiers in Cell and Developmental Biology”

This study found that Ng2+ perivascular cells in mouse skin are a diverse lineage-restricted population primarily recruited from papillary or reticular fibroblast lineages during wound healing, maintaining heterogeneity in both wounded and non-wounded skin.

research Fibroblast heterogeneity: implications for human disease

299 citations , January 2018 in “Journal of Clinical Investigation”

This review explores fibroblast heterogeneity in the mammalian dermis and suggests potential therapeutic applications by targeting fibroblast subtypes, but reports no new experimental results.

research Fibroblast Heterogeneity in Healthy and Wounded Skin

4 citations , June 2022 in “Cold Spring Harbor Perspectives in Biology”

This review discusses the heterogeneity of dermal fibroblasts in healthy mouse and human skin and reports no clinical results; the authors highlight potential insights into physiological and pathological wound healing.

research 1424 Mapping the establishment of fibroblast heterogeneity during skin development and wound repair

April 2018 in “The journal of investigative dermatology/Journal of investigative dermatology”

This study identified two distinct fibroblast subsets in mouse skin, revealing that adult skin scarring occurs due to the repair process utilizing only one, lineage-restricted fibroblast type instead of coordinated diverse populations.

community Minoxidil inhibits lysyl hydroxylase which is needed to produce collagen. If I take 2,5...5 mg of minoxidil every day can I cause my skin to age prematurely?

32 upvotes 1 year ago

Oral minoxidil is effective for hair loss and unlikely to significantly affect collagen synthesis, making it a safe option without causing premature skin aging. Users report positive hair regrowth without noticeable skin aging.
