Why do guinea pigs naturally develop collateral arteries while other species don't? Check out this wonderful preprint from our lab using in vivo Peturb-seq to discover differences in tip cell programming contribute to artery formation in guinea pig development!
Looking to join a collaborative team studying coronary artery development? Love taking pretty microscope images? The Red-Horse lab(@hhmi-science.bsky.social/Stanford) is hiring for a senior scientist to research coronary & collateral artery development apply below!: tinyurl.com/5d85xjze
If this work is interesting to you, we're hiring for a Senior Scientist with post-doctoral experience and a background in RNA molecular biology or whole-organ imaging and analysis to join our small, collaborative team! Come take more pretty pictures with us! Interested applicants should apply below:
