The invention discloses a method for lengthening, proliferating and culturing in-vitro telomeres of cartilage cells and human tissue engineering regenerated cartilage. The method and the human tissue engineering regenerated cartilage have the advantages that telomerase mRNA [(messenger RNA (ribonucleic acid)) transfection is carried out on the cartilage cells in an in-vitro manner, accordingly, the telomeres in cartilage cells obtained by means of culturing in follow-up procedures can be lengthened, proliferation and the viability of the cartilage cells and cartilage cells of elderly patients in particular can be obviously improved by the aid of synergistic effects of the telomerase mRNA transfection and small molecule compounds such as vitamin C, B18R or p65i, rapamycin and resveratrol in complete media, and the method and the human tissue engineering regenerated cartilage have important significance in improving or treating cell function decline due to senescence when the actually applied to regeneration medical treatment; the telomeres of the cartilage cells are not continuously or even frequently lengthened by the aid of the method for lengthening, proliferating and culturing the in-vitro telomeres of the cartilage cells, accordingly, genome insertion mutation risks or cell immortalization tumor formation risks can be prevented, the safety and the applicability can be greatly improved, and the method and the human tissue engineering regenerated cartilage can be effectively applied to the regeneration medical treatment.

The invention provides a construction method of immortalized cell lines of porcine subcutaneous adipose precursor cells. The method includes the following steps that primary porcine subcutaneous adipocytes are obtained; cells are cultured, and pBABE-puro-hTERT plasmids are transfected when the cell growth density is 60%-70%; after transfection for 48+ / -2 h, a 30%-serum DMEM medium containing 4 microgram / mL purinomycin used for screening; after screening for 48+ / -2 h, and liquid is changed for cultivation of the DMEM medium; after cells are cloned, the cloned cells are digested and cultured, and identification is performed until the immortalized porcine subcutaneous adipose precursor cell model is obtained. The immortalized cell lines of porcine subcutaneous adipose precursor cells can be used for adipose precursor cell proliferation, or polyester mechanism differentiation and regulation mechanism research.
