This protocol describes the method of determining basal and forskolin-stimulated lipolysis in inguinal fat pads obtained from normal chow diet (NCD) or high fat diet (HFD) ± capsaicin fed wild type mice. As an index for lipolysis, glycerol release was measured from inguinal adipose fat pads.

Laminins are the Adhesive Proteins of Basal Lamina

2023
Laminins are heterotrimeric proteins with high molecular mass found in the extracellular matrix. Each laminin molecule is composed of three chains, viz. alpha, beta, and gamma, coded by five, four, and three paralogous genes, respectively. Laminins are categories based on the compositions of the three chains. In humans, the five forms of alpha chains are LAMA 1, LAMA 2, LAMA 3, LAMA 4, and LAMA 5. The four forms of beta chains are LAMB 1, LAMB 2, LAMB 3, and LAMB 4. The three forms of gamma...

Thin-Layer Chromatography - Concepts

2020
Chromatography Chromatography is a technique used in organic chemistry to separate compounds in a mixture based on their differences in solubility between two different phases. The concept is similar to liquid-liquid extraction, except in chromatography, the two phases consist of the stationary phase and the mobile phase. The stationary phase is a solid — typically a microscale hydrogel bead — while the mobile phase is a carrier solvent. In traditional chromatography, the stationary phase is...

Layer-by-layer Collagen Deposition in Microfluidic Devices for Microtissue Stabilization

2015
The creation of functional microtissues within microfluidic devices requires the stabilization of cell phenotypes by adapting traditional cell culture techniques to the limited spatial dimensions in microdevices. Modification of collagen allows the layer-by-layer deposition of ultrathin collagen assemblies that can stabilize primary cells, such as hepatocytes, as microfluidic tissue models.
FAQs
The basement membrane anchors epidermal cells to the underlying tissue, helping maintain the attachment needed for organized skin structure. When this support is preserved, renewing cells can contribute more effectively to re-epithelialization, the restoration of epidermal coverage after injury. Damage to the attachment system can therefore interfere with repair and compromise the integrity of newly forming skin.
These cell populations contribute different functions to epidermal maintenance. Renewing keratinocytes help restore epidermal coverage, melanocytes support pigmentation, and epidermal stem cells provide regenerative capacity for ongoing repair. Protecting the basal layer preserves this combination of cellular roles, whereas injury may affect not only closure of damaged skin but also pigmentation and long-term tissue maintenance.
Injury to the basal layer can disrupt melanocyte function and lead to altered pigmentation during or after repair. It may also impair epidermal restoration, increasing the risk of barrier dysfunction. These effects show why protection extends beyond preventing visible tissue loss: maintaining the basal layer supports both the appearance of repaired skin and its ability to contribute to normal skin integrity.
Preserving the basal layer supports more effective re-epithelialization, which is the return of epidermal coverage during tissue repair. If basal structures are damaged, repair may become less effective and scarring risk may increase. This relationship makes basal layer protection relevant when clinicians balance the need to treat a skin problem against the possibility of disrupting the cells and attachments that support recovery.
Basal layer protection is particularly relevant to wound care, dermatologic procedures, and the management of skin disorders. These settings can place the epidermis at risk of mechanical, chemical, or environmental injury. Considering the basal layer during care helps clinicians focus on preserving the structures and regenerative cells that support re-epithelialization, pigmentation, skin integrity, and barrier function.
Evaluation should consider whether treatment preserves epidermal repair, pigmentation, and overall skin integrity rather than focusing only on immediate wound closure. Disruption of the basal layer or its basement membrane may impair re-epithelialization, increase scarring, or contribute to barrier dysfunction. These outcomes provide a medical framework for judging whether an intervention supports effective tissue repair.
