I'm thrilled to be co-teaching this wonderful course again this fall. Come join us at the MBL for a transformative experience!

This is going to be awesome! Can’t wait.

Information on the conference on vascular development and maintenance held in Bavaria, Germany in September 2026. Conference is held in a historical monastery on a lake in beautiful Bavaria. Registration is now open! Lots of great speakers that are leaders in the field. We will pick a large number of talks from abstracts to elevate early career investigators. Join us!

🚨 SAVE-THE-DATE 🚨

SEEON ANGIOSCIENCE! Fantastic, long-running meeting on Development & Maintenance of the Vasculature.

🗓️ Sept 2026
🌍 Bavaria, Germany

Registration open! Join us!

Biomechanics influence morphogenesis of the lung. Really cool paper by Shelby and Victor at UT Southwestern and UTD!

Diagram showing developmental stages of the chicken embryo heart, with labeled cross-sections and ventral views from stage HH6 to HH14. Coloured regions identify anatomical structures such as the paraxial and lateral head mesoderm, neural plate, neural tube, and early and late second heart field, illustrating tissue movements and the continuum between first and second heart fields during heart formation.

#DBFeature 🐣🫀

Heart cells in chick embryos emerge from a continuous field, not separate regions. Incorporation of cells into the heart depends on cell position, morphogenetic movements and break-down of tissue bridges.

The best part about science (on top of the science) is the friendships you make on the way. 🥰

Scientists coming together to share ideas, give critical feedback, and also climb mountains 😅 Thanks Li-Kun and all for coming from so far, to meet where I grew up. 🙏

Figure showing the effects of different folic acid (FA) dosages on primary ciliogenesis in various mouse embryonic fibroblast genotypes. Panels A-D present box plots quantifying ciliated cells or percent cilia under moderate and fortified FA conditions at 225, 450, and 3600 ng/mL FA in Intu+/+, Intudm/dm, Rsg1+/+, and Rsg1β13/β13 MEFs, highlighting statistically significant differences at moderate doses. Panel E displays immunofluorescence images of MEFs stained for ARL13B (red), γ-tubulin (green), and DAPI (blue), showing cilia presence and structure with scale bars indicating 15 μm and zoom-ins at 5 μm.
