Weekly reads: stem cell videos, cystic fibrosis, papers

As part of our weekly reads I’m including one of my latest videos in our Stem Cell Channel on YouTube below. This particular video fact-checks stem cell face creams, but I’ve got quite a few more including on stem cell supplements, different kinds of stem cells and more. You might …

Preventing ice contamination in the cryo-ET workflow

Cryogenic electron tomography (cryo-ET) is an imaging technique that allows reconstruction of high-resolution models of protein complexes in their near-native state. In cryo-ET, a sample (e.g. eukaryotic cells grown on an EM grid) is first vitrified, then thinned to the appropriate thickness (100-300 nm) using a Focussed Ion Beam (FIB) …

Perspectives on BioLife: one name, distinct companies

In the stem cell world some corporate names end up being very similar with the latest example being several companies with the name “BioLife.” Get a BioLife…name I guess BioLife is a catchy term. You’ve got life and biology in there in one name. Let’s deconstruct what’s going on out …

Tailoring staining protocols to electron microscopy workflows

In EM, contrast is generated when electrons interact with the sample. However, most biological material consists of light elements such as carbon, oxygen, and nitrogen, which interact with the electron beam only sparsely. To enhance the contrast of specimens and enable room-temperature EM imaging, contrasting agents are introduced. These react …
