In this paper we describe the interfacial synthesis of conjugated microporous polymers (CMP) on sacrificial substrates, and the dissolution of the substrate for the preparation of freestanding CMP nanomembranes. In addition, we will describe how the fragile nanomembranes can be transferred to other substrates.

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.

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.

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
0 Views •
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...
FAQs
Adhesion structures anchor basal cells to surrounding tissue and help maintain their position next to the basement membrane. This attachment contributes to epithelial organization by connecting the renewing cell population with its structural foundation. When adhesion is disrupted, the tissue may lose stable organization, making adhesion behavior an important feature when investigating epithelial maintenance and tissue degeneration.
Basal-layer cells must balance division with the production of differentiated descendants. Some cells replenish the basal population, while others move toward more superficial layers as they acquire specialized characteristics. This relationship links cell-cycle activity to epithelial organization: excessive or insufficient renewal can alter tissue structure, whereas coordinated differentiation supports continued replacement of overlying cells.
Positioning next to the basement membrane places basal cells at the interface between the epithelium and its supporting substrate. Their attachment helps preserve the tissue’s layered arrangement while enabling a renewing population to remain connected to its foundation. Examining this location therefore helps relate cell placement, adhesion, and epithelial integrity to abnormal remodeling or degeneration.
Studies can examine how epithelial tissues preserve their organization, replace cells, and respond when structure is challenged. They also help connect basal-cell behavior with development, wound repair, and tissue remodeling. Comparing normal and abnormal patterns may reveal whether a disorder is associated primarily with altered renewal, defective adhesion, abnormal differentiation, or a combination of these changes.
Their capacity to divide and generate differentiated cells makes basal layers relevant to restoring epithelial coverage after injury. Research can investigate how renewal replenishes lost cells and how newly generated descendants contribute to re-establishing tissue organization. The same cellular behaviors also matter during remodeling, when epithelial structure changes rather than simply returning to its previous state.
Basal layers provide a framework for studying disorders in which cell renewal, adhesion, or differentiation becomes abnormal. Tissue degeneration may involve loss of stable organization or inadequate replacement, while cancer research can examine disrupted control of these same behaviors. Analyzing the basal compartment therefore helps connect cellular abnormalities with broader changes in epithelial structure and maintenance.
