The invention discloses a trophoblast-free one-step culture method and application of tumor infiltrating lymphocytes, and particularly discloses a one-step amplification method of tumor infiltrating lymphocytes, which comprises the following steps: treating a tumor sample obtained from a subject into tumor segments; the tumor segments are cultured in a culture medium containing a CD3 agonist, a 4-1BB agonist and IL-2, so that an amplified tumor infiltration lymphocyte population is obtained, and the culture medium does not contain trophoblastic cells. Compared with the prior art, the method has the advantages that the required period for amplifying the tumor infiltrating lymphocytes is shorter, the cost is lower, the cell effect function is stronger, and the clinical application range of the tumor infiltrating lymphocyte therapy is widened.

Provided is a mammalian derived cell model which can be used in anti-aging drugs. The mammalian-derived extracembryonic trophoblast cell model is an early mammalian-derived extracembryonic stage. The change model of differentiation of cells into exoembryonic trophoblastic cells / organoids and the aging evaluation index system can be used various anti-aging research and target testing, anti-aging drug detection, screening, identification and innovative drugs / natural products Research and development of chemicals, and / or health foods and additives. It is helpful to screen and identify many resistances Candidate targets for aging can be further mechanized and functionally validated for future therapeutic use. The Screening of anti-aging drugs or natural products will produce huge economic and social benefits.
