Primary Human Pancreatic Stromal Cells

Description: Pancreatic Stellate Cells (HPaSteC) are the main fibroblastic cells of the pancreas. HPaSteC are responsible for the synthesis and the degradation of the extracellular matrix proteins that promote tissue repair. They are found adjacent to pancreatic acinar cells and around small pancreatic ducts and blood vessels. When pancreatic stellate cells are activated, they assume myofibroblast-like morphology and secrete excessive amounts of extracellular matrix proteins leading to desmoplasia in chronic pancreatitis and adenocarcinoma. Recent studies have shown that pancreatic stellate cells can also act as progenitor cells, immune cells, and intermediaries in exocrine pancreatic secretion. Additionally, pancreatic stellate cells stimulate pancreatic cancer proliferation, inhibit apoptosis, and enhance angiogenesis. Thus, pancreatic stellate cells are not only the perfect model for studying pancreatic tumor formation, but for the development of novel therapies for future treatment of chronic pancreatitis and adenocarcinoma as well. HPaSteC from Bioarray Research Laboratories are isolated from human pancreas. HPaSteC are cryopreserved after purification and delivered frozen. Each vial contains >5 x 10^5 cells in 1 ml volume. HPaSteC are characterized by immunofluorescent method with antibodies to desmin and ?-actin. HPaSteC are negative for HIV-1, HBV, HCV, mycoplasma, bacteria, yeast and fungi. HPaSteC are guaranteed to further expand for 15 population doublings in the conditions provided by Bioarray Research Laboratories.

Description: Human Pancreatic Microvascular Endothelial Cells from Creative Bioarray are isolated from human pancreatic tissue. Human Pancreatic Microvascular Endothelial Cells are grown in T25 tissue culture flasks pre-coated with gelatin-based solution for 2 min and incubated in Creative Bioarray’ Culture Complete Growth Medium generally for 3-7 days. Cultures are then expanded. Prior to shipping, cells at passage 3 are detached from flasks and immediately cryopreserved in vails. Each vial contains at least 0.5×10^6 cells per ml. The method we use to isolate endothelial cells was developed based on a combination of established and our proprietary methods. These cells are pre-coated with PECAM-1 antibody, following the application of magnetic beads pre-coated with secondary antibody.

Description: Human Primary Pancreatic Fibroblasts are isolated from normal human pancreatic tissue. Human Primary Pancreatic Fibroblasts are grown in T75 tissue culture flasks pre-coated with gelatin-based coating solution for 2 min and incubated in Creative Bioarray’ Culture Complete Growth Medium generally for 3-7 days. Cultures are then expanded. Prior to shipping, cells at passage 1 are detached from flasks and immediately cryo-preserved in vials. Each vial contains at least 0.5x10^6 cells per ml.

Description: Human Pancreatic Epithelial Cells from Creative Bioarray are isolated from normal human pancreatic tissue. Human Pancreatic Epithelial Cells are grown in T25 tissue culture flasks pre-coated with gelatin-based coating solution for 2 min and incubated in Creative Bioarray’s Culture Complete Growth Medium generally for 3-7 days. Cultures are then expanded. Prior to shipping, cells at passage 3 are detached from flasks and immediately cryo-preserved in vials. Each vial contains at least 0.5x10^6 cells per ml. Cells can be expanded for 3-7 passages at a split ratio of 1:2 or 1:3 under the cell culture conditions specified by Creative Bioarray. Repeated freezing and thawing of cells is not recommended.

Description: Human Pancreatic Islets are isolated from the pancreas of human using Collagenase P and purified using Ficoll density gradient.

Description: GFP Expressing Human Pancreatic Microvascular Endothelial Cells (GFP-HPaMVECs) provided by Creative Bioarray are puromycin-selected from Human Pancreatic Microvascular Endothelial Cells infected with lentivirus expressing GFP. GFP-HPaMVECs are cryopreserved in passage 4 and guaranteed for at least 18 population doublings under the cell culture conditions specified by Creative Bioarray. These cells are characterized by immunofluorescence staining with antibody of VWF/Factor VIII and PECAM1. These cells are negative for mycoplasma, bacteria, yeast, fungi, HIV-1, hepatitis B and hepatitis C.
