Organoids

CytoGrow™ growth factors enhance intestinal organoid growth

A.

B.

A. Comparison of CytoGrow™ growth factors and other growth factors in supporting the growth of intestinal organoids in Matrigel. The organoid grown in the CytoGrow™ system shows a bigger size and faster growth rate within 6 days. B. The curve of organoid growth area within 6 days, showing the fast growth of Intestinal organoid with CytoGrow growth factors. ​

CytoGrow™ growth factors support intestinal organoid growth

Intestinal organoids grown in Matrigel were cultured with organoid growth medium supplemented with CytoGrow™ growth factors. The video shows the expansion of the organoids over 6 days. ​ ​

CytoGrow™ growth factors support the different polarities of organoid morphologies​

A.

B.

CytoGrow™ growth factors support the Apical-in (A) and Apical-out (B) morphologies of intestinal organoid grown in Matrigel (A) and VitroGel® (B), respectively. ​

CytoGrow™ growth factors used in differentiation of iPSC derived intestinal organoids.

Representative image showing iPSC derived intestinal organoids cultured in VitroGel® ORGANOID. iPSC cells were cultured in VitroGel® STEM to generation of spheroids cells. The spheroids were then differentiated to intestinal organoids using CytoGrow™ growth factors. Yellow fluorescence: Phalloidin, Magenta: Villin protein, Blue staining (DAPI) represents cell nuclei.

Neuronal Culture

CytoGrow™ growth factors support the development of Dopaminergic Neuron Progenitors (DNPs) on 2D thin coating surface with VitroGel® NEURON hydrogel

A.

A. Video shows robust survival of DNP colonies, and elaboration of neurites; B & C. IncuCyte Neurotrack analysis software was used to quantify the expansion of the area of DNP colonies, and their enhanced complexity of neurite elongation. ​

CytoGrow™ growth factors support the 3D development of dopaminergic neurons encapsulated in VitroGel® NEURON hydrogel.

A.

B.

iPSCs were 3D cultured in VitroGel® STEM with RocketCell™ IPSC Xeno-Free Growth Medium (Cat. No. RC02-GM) for 6 passages and were differentiated into Floor Plate Neuro-Epithelial Spheroids. The spheroids were recovered from the hydrogel using the VitroGel® Organoid Recovery Solution and embedded in VitroGel® NEURON.

A. Brightfield images of spheroid on day 0 (A, left) that were differentiated for 16 days (A, right). B. The samples were fixed and stained with beta-III-tubulin antibody and DAPI, depicting that the majority of the spheroids are neurons with the ability to form axonal connections. The cultures were visualized with the Keyence BZ-X microscope at 4X and 10X magnifications. ​

Stem Cell Culture

Comparison of micrographs and growth of IPSC colonies cultured in CytoGrow™ and other growth factors.

The 6-well plate was placed into an Incucyte S3 and scanned using “Whole Well” function for both brightfield and red fluorescence. The resulting pictures were analyzed usingan algorithm to detect colonies.​

Confocal imaging of IPSC spheroids growing in VitroGel® STEM.

IPSC cultures were plated in VitroGel® STEM and grown for 5 days. The slides were imaged using a Leica Mica confocal microscope. An IPSC spheroid was imaged in 3D using the Z-stacking function, and images for Hoechst 33342 (DNA), Tra-1-60 (Podocalyxin, cell surface), Lin28A (cytoplasmic RNA binding protein), and Oct4 (nuclear transcription factor) were projected using the maximum intensity algorithm. ​
