Definitions
- the invention belongs to the technical field of tissue and organ reconstruction, and particularly relates to a method for constructing a bioengineered salivary gland organ and an acinoid based on human small salivary gland stem cells.
- Human salivary glands mainly consist of three large salivary glands and many small parotid glands distributed under the oral mucosa. They are composed of parenchyma (acinus, duct) and stroma (connective tissue, blood vessels, lymphatic vessels, nerves, etc.). Studies on stem cells in salivary glands have focused on large salivary glands. It has been experimentally confirmed that mesenchymal stem cells exist in human parotid glands and can be induced to differentiate into osteogenic, adipogenic and chondrocytes in vitro. This is another new source of mesenchymal stem cells.
- pluripotent progenitor cells isolated from the submandibular gland have stem cell characteristics and can differentiate into endoderm cells. They are implanted into the liver through the portal vein and found to be integrated into the trabecular bone and secrete albumin.
- salivary gland cells were isolated from the submandibular glands of murine animals and cultured in vitro by a floating sphere culture system containing cells expressing stem cell markers Sca-1, c-Kit and Musashi-1, and confirmed that these stem cells were derived from the ductal epithelium. In vitro, these cells differentiate into salivary gland duct cells and acinar cells that secrete mucin and amylase.
- the stem cells were enriched by labeling flow cytometry with c-Kit, and these cells were differentiated into acinar cells secreting amylase in vitro. Intra-gieririal injection of small amounts of c-Kit+ cells in the body results in long-term recovery of salivary gland morphology and function. This indicates that the salivary gland contains two kinds of stem cells, mesenchymal stem cells and epithelial stem/progenitor cells. Although these studies confirmed the presence of these two types of stem cells in large salivary gland tissue, it is clinically difficult to obtain an appropriate amount of tissue from the large salivary glands to isolate and culture these stem cells.
- the submucosal parotid gland has homology with large salivary gland tissue: it began to be cut in the 1980s. A biopsy of the mucous glands of the lips was performed to diagnose some of the diseases of the large salivary glands, indicating the homology of the small parotid glands with the large salivary glands.
- the cell components of the small parotid gland under the mucosa are the same as those of the large salivary gland. They are composed of acinar cells, ductal epithelial cells, myoepithelial cells and mesenchymal cells. In theory, the small parotid gland should also contain the above. Two kinds of stem cells.
- the small parotid glands under the mucosa are widely distributed, the source is rich, the material is easy to obtain, the surgical trauma is small, the donor area is concealed, and the function of the donor area is basically not affected after cutting.
- Organ-like units are structures formed by three-dimensional culture in vitro in an extracellular matrix with various cell types in tissues. This method is widely used in the study of small intestinal stem cells and tissue engineering construction. It has been reported in the literature that small intestinal stem cells isolated from Lgr5+ can differentiate into organ-like units in Matrigel. After detecting this type of organ unit, it was found to have different cell types, including intestinal epithelial cells, mucus secreting cells and endocrine cells, and a intestinal-like structure was observed. Based on this, the researchers conducted research on tissue engineering small intestine and various stem cell proliferation and differentiation. Recently, some scholars obtained epithelial cells and mesenchymal cells from the submandibular glandular tissue of mouse embryos from 13.5 days to 14 days.
- the two cells were put together for three-dimensional culture in vitro, and three days later, bioengineered salivary gland buds were formed, and then Transplanted orthotopically into the submandibular gland or parotid gland, a mature functional salivary gland is formed in the body 30 days after transplantation.

- the enzymatically digested mesenchymal stem cells and epithelial stem/progenitor cells were single cell suspensions, counted, resuspended in medium, mixed with an equal volume of 4 ° C thawed Matrigel, seeded in 24-well plates, and placed in a 37 ° C cell culture incubator. After 20 minutes, the cells were coagulated with Matrigel, and the medium was added. Each well was inoculated with 2.5 ⁇ 10 5 small mesenchymal stem cells and 2.5 ⁇ 10 5 small parotid epithelial stem/progenitor cells, mixed with 50 ⁇ L of Matrigel, and inoculated successfully.
- the liquid was changed every other day, and after one day of in vitro culture, the cells aggregated into a branch shape, and after 3 days, organoid formation of the alveolar and tubular branch structures was observed. It can grow to the maximum in 6-10 days, and can be switched to salivary gland medium after 6 days to promote its differentiation and maturation.
- the specific operation step of three-dimensionally culturing the human parotid epithelial stem/progenitor cells in the basement membrane matrigel is: digesting the small salivary gland epithelial stem/progenitor cells cultured to three or more generations into single cells Inoculated in Matrigel, cultured with keratinocyte culture medium, the specific operation is trypsin digestion of epithelial stem/progenitor cells as single cell suspension, counted, resuspended in medium, and mixed with an equal volume of 4 ° C thawed Matrigel, Inoculate in a 24-well plate and place in a 37 °C cell culture incubator.
