Embodiment Construction

[0041] Hereinafter, the present invention will be further described with reference to the drawings and specific embodiments to better understand the present invention.

[0042] 1. Experimental materials:

[0043] Human skin fibroblasts (HFF), hiPS cells (HFF-derived-iPSCs) induced by retroviral method.

[0044] 2. Primer screening

[0045] 1. Screening of primers for detection of endogenous pluripotent genes by fluorescence quantitative PCR for Oct4, Sox2 and Nanog

[0046] Design multiple pairs of primers with amplified fragments of about 150 bp for the endogenous genes Oct4, Sox2 and Nanog of pluripotent stem cells. According to the conventional Trizol method, the total RNA of hiPS cells was extracted and reverse transcribed into cDNA, and each pair of designed primers was used for amplification. Increase each pair of primers with 2 to 3 repeats.

[0047] The amplification system is as follows:

[0048] 2×SYBR Premix Ex Taq

10μL

Upstream and downstream primers

0.2μM each

Abstract

The invention relates to a primer composite for identifying human induced pluripotent stem cell pluripotent genes, a kit and a detection method. The primer group comprises a primer group A, a primer group B and a confidential reference primer, wherein the primer group A comprises one or several kinds of primer pairs for amplifying human inducted pluripotent stem cell endogenous genes Oct4, Sox2 and Nanog; the primer group B comprises one or several kinds of primer pairs for amplifying Oct4, Sox2 and Nanog general genes; the confidential reference primer is a primer for amplifying a GAPDH gene.Concretely, RNA (ribonucleic acid) is extracted from the pluripotent stem cells; a real-time PCR(polymerase chain reaction) technology is used by the detection method and the kit for performing quantitative determination on the pluripotent gene so as to identify the endogenous and exogenetic pluripotent gene expression differences. By using the identification method provided by the invention, theoperation is simple; the cost is low; the accuracy and the sensitivity are high.

Description

Technical field [0001] The present invention relates to the field of biotechnology, in particular to a detection primer set, kit and detection method for identifying the expression of endogenous and exogenous pluripotency genes in pluripotent stem cells. Background technique [0002] Pluripotent Stem Cells (PSCs) are a class of cells that have self-renewal and differentiate into a variety of cell tissues, mainly including embryonic stem cells (Embryonic Stem Cells, ESCs) and induced pluripotent stem cells (iPSCs) . ESCs are obtained by isolating the inner cell mass of blastocysts or primordial germ cells. iPSCs are self-renewing and pluripotent cells obtained by expressing specific transcription factors in differentiated somatic cells to induce their reprogramming. The establishment of iPSCs technology avoids ethical barriers. It not only provides unique tools for the study of differentiation potential mechanisms and normal development in basic research, but also has great poten...
