Differentiation of Human Embryonic Stem Cells into Cone Photoreceptors
[Abstract]  Photoreceptors are specialized retinal neurons able to respond to light in order to generate visual information. Among photoreceptors, cones are involved in colors discrimination and high-resolution central vision and are selectively depleted in macular degenerations and cone dystrophies. A possible therapeutic solution for these disorders is to replace degenerating cells with functional cones. Here, we describe a simple protocol for the rapid production of large amount of cone photoreceptors from human pluripotent stem cells. The differentiation protocol is based on the “default pathway” of neural induction using the BMP, TGFβ and WNT antagonist COCO.

[14C] Linoleic Acid Uptake and Fractionation Assay in Vibrio cholerae
[Abstract]  The gram-negative curved bacillus Vibrio cholerae (V. cholerae) causes the severe diarrheal illness cholera. The work presented here is to assess whether unsaturated fatty acids (UFAs), such as linoleic acid, have the potential to directly affect proteins involved in DNA binding because they are able to enter the cell. In this protocol, we show how to measure linoleic acid entering V. cholerae when added exogenously and determine whether it is able to enter the cytoplasm. This protocol will quantify how much linoleic acid is able to enter the cell and then identify the amount of linoleic acid that stays in the membrane or ultimately enters the cytoplasm.

Preparation of Candida albicans Biofilms for Transmission Electron Microscopy
[Abstract]  Transmission Electron Microscopy is a form of microscopy that allows for imaging of distinct portions of an individual cell. For Candida albicans biofilms, it is often used to visualize the cell walls of fixed samples of yeast and hyphae. This protocol describes how to grow, harvest, and fix Candida albicans biofilms in preparation for Transmission Electron Microscopy.
