ABSTRACT
Mammary epithelial cells are the only cells in the mammary glands that are capable of lactation and they are ideal for studying cellular and molecular biology mechanisms during growth, development and lactation of the mammary glands. The limiting factors in most of the currently available mammary epithelial cells are low cell viability, transgenerational efficiency and lactation function that renders them unsuitable for subsequent studies on mammary gland's cellular and lactation mechanisms and utilizing them as bioreactors. Hence, new methods are required to obtain mammary epithelial cells with high transgenerational efficiency and lactation function. In this study, transdifferentiation of goat ear fibroblasts (GEFs) into goat mammary epithelial cells (CiMECs) was induced in only eight days by five small molecule compounds, including 500 µg/mL VPA, 10 µM Tranylcypromine, 10 µM Forskolin, 1 µM TTNPB, 10 µM RepSox. Morphological observation, marker genes comparison, specific antigen expression and comparison of gene expression levels by transcriptome sequencing between the two types of cells that led to the primary deduction that CiMECs have similar biological properties to goat mammary epithelial cells (GMECs) and comparatively more lactation capacity. Therefore, we establish a novel reprogramming route to convert fibroblasts into CiMECs under fully chemically conditions. This study is expected to provide an in vitro platform for understanding cellular mechanisms such as mammary epithelial cells' fate determination and developmental differentiation, and also to find a new way to obtain a large number of functional mammary epithelial cells in vitro.
