Human Primary Rectal Epithelial Cells

Cell Details

The rectum is a large intestine that is 375px upward from the anal verge. The rectum is multi-fat, no longitudinal, and is located on the dorsal side of the bladder and reproductive organs. The cross-section of the rectum is from the inside to the outside: mucous membrane (epithelial layer, lamina propria, mucosal muscle layer), submucosa, muscular layer, adventitia. Among them, epithelial cells are mainly located in the epithelial layer of the mucosa, which is a single columnar epithelium containing more goblet cells.

Cell Characteristics

1) The cells are derived from normal rectal tissue that has been surgically removed.

2) Cell identification: broad-spectrum keratin (PCK) immunofluorescence staining was positive.

3) The purity of the identified cells is higher than 90%.

4) Does not contain HIV-1, HBV, HCV, mycoplasma, bacteria, yeast and fungi.

5) Cell growth mode: paving stone, polygonal cells, adherent culture.

Transportation and Preservation

Depending on the weather conditions and the distance of transportation, the company negotiates with the customer and chooses one of the following methods.

1) 1mL of frozen cell suspension is placed in a 1.8mL cryotube and placed in a foam incubator filled with dry ice for transport; after receiving the cells, thaw the resuscitated cells as soon as possible for culture. If resuscitation is not possible immediately, Cryopreserved cells can be stored at -80°C for 1 month.
2) T-25 culture flask is filled with complete medium and then transported at room temperature. After receiving the cells, please observe the growth state of the cells under a microscope. If the bottle filling rate exceeds 85%, please carry out the subculture immediately. If there are more cells in suspension, allow the flask to stand overnight in the incubator to help the undead suspension cells to reattach.
