TLDR
It is probable that at the molecular level the terminal web is formed by elongated branching elements that endows the apex with mechanical stability and anchors it to the body of the cell.About:

Organization of an actin filament-membrane complex. Filament polarity and membrane attachment in the microvilli of intestinal epithelial cells.
M S Mooseker,L G Tilney +1 more
TL;DR: Through the analysis of isolated, demembranated brush borders decorated with the myosin subfragment, S1, it is determined that all the microvillar actin filaments have the same polarity.

Villin is a major protein of the microvillus cystoskeleton which binds both G and F actin in a calcium-dependent manner
Anthony Bretscher,Klaus Weber +1 more
TL;DR: The properties of villin are not compatible with its previously suggested role as the cross-filament between the microvillus microfilament core and the plasma membrane, but rather indicate a function as a calcium-dependent F actin-bundling protein.

Identification and Characterization of Epithelial Cells in Mammalian Tissues by Immunofluorescence Microscopy Using Antibodies to Prekeratin
TL;DR: The widespread, if not general occurrence of cytokeratin filaments in epithelial cells is emphasized, and it is proposed to use this specific structure as a criterion for true epithelial character or origin.
Journal ArticleDOI
Decreases in tubulin and actin gene expression prior to morphological differentiation of 3T3 Adipocytes
TL;DR: Examination of the synthesis and accumulation of cytoskeletal proteins and of their temporal relation to morphological conversion indicates that the biosynthetic changes are very early events in the differentiation, and suggests strongly that they participate in the development of the adipocyte morphology.

The role of calcium in the isolation of brush borders from epithelial cells of rat small intestine
TL;DR: It was found that there was no precise optimum concentration for EDTA but a separation could not be obtained below 2-4 mM/1 and the onset of the ability to release brush borders coincided approximately with the ionization of the third acid radical of the chelating agent.

TL;DR: The “cell web,” a supporting fibrillar component of the cytoplasm was investigated in sections of adult rat kidney stained with the TPA technique, and some coarse fibrils, oriented circularly around the tubule, were seen close to the basement membrane.

Über Doppelbrechung und Feinbau der Darmepithelzellen der Kaulquappe
TL;DR: Die Stäbchen im Saum des Darmepithels der Kaulquappe sind in frischem Zustand positiv doppelbrechend in bezug auf ihre Länge, die Stärke ihrer Doppelbrechung nimmt im aufgehellten Dauerpräparat wesentlich ab (FormdoppelBrechung).
