Determination of minimum serum concentration to develop scaffold free micro-tissue
Research Overview
High serum and growth-factor concentrations can mask the biological cues that actually drive microtissue formation. This study asked how little serum is needed, forming human umbilical vein endothelial cell (HUVEC) microtissues with the 3D Petri Dish® technique in media containing 0%, 1%, 5%, or 10% fetal bovine serum.
Live/dead analysis was performed on day 7, and micrographs from days 1, 3, 5, and 7 were quantified in ImageJ to track microtissue size over time — yielding practical guidance on the minimum serum concentration compatible with endothelial microtissue formation, useful for defined-medium and serum-reduction protocols.
Key Discoveries
- HUVEC microtissues formed in 0%, 1%, 5%, and 10% fetal bovine serum for direct comparison
- Live/dead viability assessed at day 7; size tracked by image analysis on days 1, 3, 5, 7
- Identifies minimum serum needed, supporting reduced-serum and defined-medium protocols
