EC-Cult-XF Culture Kit

Built around a xeno-free basal medium and matched growth supplements, this endothelial cell culture system from STEMCELL Technologies offers a fully defined, animal component-free environment for in vitro expansion of human endothelial cells. The kit supports cord blood-, peripheral blood-, and vascular-derived endothelial progenitors as well as mature endothelial populations, preserving canonical surface markers such as CD31, CD144, and KDR across multiple passages.

Researchers working in vascular biology, regenerative medicine, and tissue engineering apply the system for colony-forming assays, tube formation studies, and matrix-gel angiogenesis screens. By eliminating serum and animal-derived hydrolysates, the formulation reduces lot-to-lot variability and aligns laboratory workflows with translational pipelines targeting clinical-grade cell manufacturing. Each kit provides enough reagents for routine passaging routines; the frozen supplement aliquot is held at -20°C while the basal medium is kept refrigerated until first use.

Typical seeding densities of 1-2 x 10^4 cells/cm² on tissue culture-treated surfaces yield confluent monolayers within 5-7 days under standard 37°C, 5% CO₂ incubation. Recommended handling includes thaw-on-ice for supplement vials, single-use aliquoting to limit freeze-thaw cycles, and protection of light-sensitive growth factors from ambient light. Complete protocols, including coating matrix recommendations and passaging guidance, are provided in the product insert.
