Description

Basement membranes are continuous sheets of specialized extracellular matrix that form an interface between endothelial, epithelial, muscle, or neuronal cells and their adjacent stroma. Basement membranes are degraded and regenerated during development and wound healing. They not only support cells and cell layers, but they also play an essential role in tissue organization that affects cell adhesion, migration, proliferation, and differentiation. Basement membranes provide major barriers to invasion by metastatic tumor cells.

Mogengel Matrigengel MatrixHCis a soluble form of basement membrane purified from Engelbreth-Holm-Swarm (EHS) tumor.Mogengel Matrigengel MatrixHCat 37 °C to form a reconstituted basement membrane. The major components of Mogengel Matrigengel MatrixHCinclude laminin, collagen IV, entactin, and heparin sulfate proteoglycan.

 

Intended Use

This series is divided into standard high concentration and low factor high concentration, their concentration and viscosity are higher than the ordinary concentration of matrix glue, which is more suitable for in vivo experiments (animal models), such as PDX, CDX, in vitro angiogenesis assays.

Coating Procedures

Thaw Matrigengel Matrix overnight at 2-8 °C. Refrigerator temperatures may vary, therefore it is recommended to keep Matrigengel on ice in a refrigerator during the thawing process. Thawed Matrigengel solidifies quickly at temperatures above 15 °C; when working with Matrigengel,

keep it on ice to prevent untimely gelling.

There are many applications for Matrigengel which require different thicknesses and concentrations. A thick gel is needed for applications such as endothelial cell formation of capillary-like structures (Tube Formation Assay), the differentiation of rat aorta tissue into capillary-like structures (Aortic Ring Assay), epithelial organoid formation, or tumor organoid formation. Some applications, such as propagation of primary cells, require a thin layer coating and not a thick gel; therefore, the thin layer method should be used.

 

Thick Gel Method:

1. Thaw Matrigengel as stated above.

2. Mix Matrigengel by slowly pipetting solution up and down; be careful not to introduce air bubbles.

3. Pipette 200-300 μL per cm2 onto the growth surface.

4. Place coated object at 37 °C for 30 minutes.

5. Coated objects are ready for use.

 

Thin Layer Method (non-gelling):

1. Thaw Matrigengel as stated above.

2. Mix Matrigengel by slowly pipetting solution up and down; be careful not to introduce air bubbles.

3. Dilute Matrigengel to desired concentration in cold serum-free medium. A 1:100 dilution is recommended for the propagation of primary cells. Empirical determination of the optimal coating concentration for your application may be required.

4. Add a sufficient amount of solution to cover the entire growth surface area. A volume of 300 µL per cm2 is recommended.

5. Incubate coated object at room temperature for one hour.

6. Aspirate coating solution and immediately plate cells. Do not allow coated surface to dry out.

 

Example for PROCEDURES:

Subcutaneous tumor formation in mice

1. Equipment, reagents and consumables

1.1. Equipment: Biosafety cabinet, cell incubator, low temperature horizontal centrifuge, inverted microscope

1.2.Reagents:Matrigengel(Cat:082724/082726/082723/082721),basic medium,medium containing 10% fetal bovine serum, 1×PBS, Trypsin Solution

1.3.Consumablessterile pipette tips; 10cm cell culture dish; Sterile EP tube; Disposable syringes and other consumables can be adjusted according to the experimental design

2. Experimental contents and methods

2.1.Put the Matrigengel in the ice box and put it in the refrigerator at 4℃ so that the glue can slowly melt overnight;

2.2. Select cells in good condition and growth logarithmically, discard the supernatant, add 2 mL 1×PBS solution to wash gently, discard the liquid;

2.3. Add 1 mL 0.25% trypsin cell digestion solution into the petri dish, let it stand for 10 seconds, discard the trypsin, and continue digestion at room temperature for 1~3 minutes with the residual trypsin.

2.4. When the cells become round (keep in mind that they cannot be digested until the cell edge is clear), add 1 mL medium containing 10% fetal bovine serum to terminate digestion. Carefully blow the cells apart and collect the cell suspension into a 15 mL plastic centrifuge tube.

2.5. Centrifuge at 1000 rpm for 3 minutes and discard the supernatant. After washing the cells with PBS for one time, the cells were re-suspended by adding serum-free basal medium, and 10 μL cell suspension was taken for cell count.

2.6.HepG2 cellsEach mice should be vaccinated 5 million cells. According to cell density, the required cell suspension was placed in a sterile 1.5mL plastic centrifuge tube at 1000 rpm for 3 min. The supernatant was discarded and the serum-free medium or PBS was added until the total volume was 300μL.

HCT - 116 cells:Each mice should be vaccinated 1 million cells. According to cell density, the required cell suspension was placed in a sterile 1.5mL plastic centrifuge tube at 1000 rpm for 3 min. The supernatant was discarded and the serum-free medium or PBS was added until the total volume was 300μL.

MIA - PaC - 2 cellsEach mice should be vaccinated 10 million cells. According to cell density, the required cell suspension was placed in a sterile 1.5mL plastic centrifuge tube at 1000 rpm for 3 min. The supernatant was discarded and the serum-free medium or PBS was added until the total volume was 500μL.

2.7.Mixing of the Matrigengel: Cell suspension and Matrigengel are mixed in a 1:1 ratio at 4℃.

2.8.Subcutaneous injection: The nude mice were fixed with the left hand and injected subcutaneously into the right back of the nude mice. During inoculation, the needle was inserted a little deeper into the subcutaneously, about 1 cm deep, to reduce the overflow of cell suspension from the eye after injection, and the inoculation volume was 100μL. MIA-PaC-2 cells were injected 200 μL/ piece.

2.9. Recording data: The nude mice were put back into the cage for further feeding, the tumor volume was measured regularly according to the experimental requirements, the data was recorded to make a curve, and the nude mice were euthanized before the tumor volume was less than 2000 mm3, and the tumor was removed and photographed.
