Reconstructing 3D Living Biomaterials

Hydrogel Solutions for Tissue Reconstruction and Repair

Alphabioregen/Neuromics are pleased to announce the use of our Hydrogels for reconstructing living biomaterials for regenerative biology and medicine: Suwan N. Jayasinghe,Jensen Auguste, Chris J. Scotton. Platform Technologies for Directly Reconstructing 3D Living Biomaterials. DOI: 10.1002/adma.201503001.

In this study, researchers use our  Collagen Hydrogel, Collagen Hydrogel Soft and Collagen Hydrogel Soft+  to describe  in vivo applications using a murine model to interrogate biocompatibility and cellular behavior post-transfer.

Luc macrophages (CC or BES) were then incorporated into a fl uid mixture containing one of three alternative collagen-based hydrogels, namely, Collagen Hydrogel, Collagen Hydrogel Soft, or Collagen Hydrogel Soft+ (resulting in six possible combinations of macrophages and biopolymer).

Overview of Results



Figure: Bioluminescent imaging of implanted macrophage–biopolymer mixes. IC-21-Luc macrophages (CC or BES) were mixed with biopolymer (Hydrogel, Soft, or Soft+) and subcutaneously injected into the dorsal fl anks of C57Bl/6 mice (three mice per hydrogel, with CC on the left fl ank and BES on the right). Following intraperitoneal injection of delta-luciferin, macrophage bioluminescence was detected using an IVIS Lumina II imaging system. A representative image from day 1 post-implantation (and 25 min post luciferin injection) is shown, indicating the peak detectable radiance (photons s −1 cm −2) in identically sized regions of interest. The CE results were very similar to the BES implants.


Figure:  Histological analysis of the macrophage–biopolymer implantation site (MSB staining). At day 4 post-implantation, skin was harvested from each dorsal fl ank, and processed for histology. Where possible, serial sections directly adjacent to those shown in Figure 4 were stained with a modifi ed trichrome stain. Mature fi brillar collagen within the dermis appeared dark blue, while the collagen within the hydrogel was generally lighter blue in appearance, indicating a less highly cross-linked or fi brillar form of collagen. Scale bar: 200 µm.

These Collagen Hydrogels are proving easy to use and effective in the hands of our customers.

Potent and Pure HUVECs

Only $199 for 500,000 Cells Through Sept. 30

HUVECs (Human Umbilical Vein Endothelial Cells) assays are important for studying the pathology of many diseases and cancers. We provide fresh cells at P1 in T25 flasks. They come to you ready to culture. Initial customer feedback has been favorable regarding ease of culturing and doubling cell populations (up to 16 passages). Now is the time to invest and build your stock of HUVECs!

Characterization of the cells:
  • Cytoplasmic VWF / Factor VIII: 95% positive by immunofluorescence 
  • Cytoplasmic uptake of Di-I-Ac-LDL: 95% positive by immunofluorescence 
  • Cytoplasmic PECAM1: 95% positive by immunofluorescence 
HUVECs are negative for HIV-1, HBV, HCV, and mycoplasma.

Questions? Contact information: Pete Shuster, CEO and Owner, Neuromics-phsuster@neuromics.com or direct phone: 612-801-1007.

From Zero to 3-D Cell Based Assays in 15 Minutes

Collagel Hydrogels are Designed to Match Your Cell Types.

We are pleased to add Collagel Hydrogels to our 3-D Cell Based Assay Solutions.

The are 3 different gel types that mimic the different in vivo extracellular environment that your cells experience. You will be able to get really nice adipogenesis with MSCs using our CollaGel Hydrogel Standard. CollaGel Hydrogel Soft is an ideal matrix for growing fibroblast; primary hepatocyte cultures and great for growing smooth muscle cells. CollaGel Hydrogel Soft+ is an ideal matrix for growing nervous cells, veins cells and Hydroxyapatite crystals.

Using these gels, you can now form small tube-like structures in combination with Human Umbilical Vein Endothelial Cells (HUVEC) in a 3D model. Our CollaGel Hydrogel can also be used for 3D printing without worrying about the needles in your machine been broken due to the fast gelling process. Collagel Hyrogels can be used for: Stem Cell Behavior Studies Fibrosis Studies,  Cosmetic Toxicology, Hepatocyte Assays, Neuronal Branching, Wound Healing Assays, Cell Invasion Assays, Migration Assays, Cancer Cell Phenotyping and  Bioprinting.

I will be posting Collagel Hydrogel related data and images provided by our customers.
