Embodiment 1
[0062] Example 1: Multiple transplantation of plant and protein-induced hematopoietic stem cells into the tail vein improves the body function of SAMP8 rapidly aging mice and prolongs the lifespan of SAMP8 rapidly aging mice
[0063] Senescence accelerated mouse (SAM) is an inbred aging model mouse obtained by Professor Takeda of Kyoto University in Japan for more than 20 years, including SAMP (senescence accelerated-prone mouse, SAMP) and SAMR (senescence accelerated mouse). -resistant mouse, SAMR) two strains. After passing through the growth period (about 4 to 6 months old), SAMP8 rapidly exhibits aging characteristics: from reactivity, passive escape response, fur luster, fur roughness, hair loss, skin ulcers, eye damage, corneal opacity, Corneal ulcers, cataracts, kyphosis and many other special signs and manifestations related to aging are commonly used animal models for research on aging and anti-aging.

Embodiment 2
[0080] Example 2: Using plant and protein-induced autologous hematopoietic stem cell tail vein transplantation to improve the vitality of nude mice and prolong the life span of nude mice
[0081] Balb / c nude mice lack thymus, and because there are only thymus remnants or abnormal epithelium, T cells cannot differentiate normally, so T cells are immune deficient and have a limited lifespan. Due to the susceptibility to severe infection, nude mice can only be raised and survived in a very clean (SPF grade for short) environment. Hematopoietic stem cells are the origin of all blood cells and immune cells. In this study, autologous hematopoietic stem cells induced by plants and proteins were repeatedly transplanted intravenously, and the survival and lifespan of Balb / c nude mice were observed.
[0082] Experimental grouping design and stem cell transplantation method:
[0083] The same batch of 40 2-month-old Balb / c-nu nude mice was purchased from the Department of Experiment...
Embodiment 3
[0099] Example 3: Using plant and protein-induced autologous hematopoietic stem cell tail vein transplantation to delay the aging speed of natural aging Bal b / c mice and significantly prolong lifespan
[0100] 1. experimental method:
[0101] 1) Use the same batch of 60 12-month-old Balb / c mice, randomly group them into blank control group (20 mice), and PPiHPS experimental group (40 mice);
[0102] 2) 58 Balb / c mice aged 20 months in the same batch were randomly divided into blank control group (18 mice) and PPiHPS experimental group (40 mice);
[0103] For normal feeding, the blank group was injected with 0.1ml normal saline into the tail vein, once every 60 days; the experimental group was transplanted with 2x 10 tail veins. 7 PPiHPS, once every 60 days. All Balb / c mice in this experiment were purchased from the School of Radiology Medicine, Chinese Academy of Medical Sciences (Tianjin), animal certificate number: SCXK (Jin) 2010-0002.
