Distribution of Glycan Motifs at the Surface of Midgut Cells in the Cotton Leafworm (Spodoptera littoralis) Demonstrated by Lectin Binding [PDF]
Frontiers in Physiology, 2017 Glycans are involved in many biological phenomena, including signal transduction, cell adhesion, immune response or differentiation. Although a few papers have reported on the role of glycans in the development and proper functioning of the insect midgut,

Dynamic microvilli sculpt bristles at nanometric scale
Nature CommunicationsOrganisms generate shapes across size scales. Whereas patterning and morphogenesis of macroscopic tissues has been extensively studied, the principles underlying the formation of micrometric and submicrometric structures remain largely enigmatic ...

Pre-implantation mouse embryos cultured In vitro under different oxygen concentrations show altered ultrastructures [PDF]
, 2020 Assisted Reproductive Technologies routinely utilize different culture media and oxygen (O2) concentrations to culture human embryos. Overall, embryos cultured under physiological O2 tension (5%) have improved development compared to embryos cultured ...

Direct visualization of epithelial microvilli biogenesis [PDF]
Current Biology, 2020 SUMMARYMicrovilli are actin bundle supported surface protrusions that play essential roles in diverse epithelial cell functions. To develop our understanding of microvilli biogenesis, we used live imaging to directly visualize protrusion growth at early stages of epithelial differentiation. Time-lapse data revealed that an “initiation complex” enriched

Retinal Pigment Epithelial Cell Line with Fast Differentiation and Improved Barrier Properties
Pharmaceutics, 2019 Retinal pigment epithelium (RPE) acts as an outer blood−retinal barrier that limits the access of circulating xenobiotics to the eye. In addition, the RPE limits posterior elimination of intravitreally injected drugs to circulation.

Isolation of microvilli from mammalian cells [PDF]
FEBS Letters, 1978 Microvilli have a variety of functions in animal cells. On epithelial cells of the renal tubule or small intestine, they increase the absorptive capacity of the cell, by increasing its surface area. In this instance, microvilli are concentrated at one end of the cells, in the form of ‘brush border’, and may be isolated as such and their composition ...

Insights into the origin of metazoan filopodia and microvilli. [PDF]
, 2013 Filopodia are fine actin-based cellular projections used for both environmental sensing and cell motility, and they are essential organelles for metazoan cells. In this study, we reconstruct the origin of metazoan filopodia and microvilli.
