Abstract
Since their discovery, mesenchymal stromal cells (MSCs) have received a lot of attention, mainly due to their self-renewal potential and multilineage differentiation capacity. For these reasons, MSCs are a useful tool in cell biology and regenerative medicine. In this article, we describe protocols to isolate MSCs from bone marrow (BM-MSCs) and adipose tissues (AT-MSCs), and methods to culture, characterize, and differentiate MSCs into osteoblasts, adipocytes, and chondrocytes. After the harvesting of cells from bone marrow by flushing the femoral diaphysis and enzymatic digestion of abdominal and inguinal adipose tissues, MSCs are selected by their adherence to the plastic tissue culture dish. Within 7 days, MSCs reach 70% confluence and are ready to be used in subsequent experiments. The protocols described here are easy to perform, cost-efficient, require minimal time, and yield a cell population rich in MSCs.
Keywords: Adipose tissue (脂肪组织)Background
The concept of stem cells dates back to the 19th century, but their existence was confirmed in the 1960s and 1970s following experiments by Friedenstein and collaborators, which showed the presence of stem cells in the bone marrow (Friedenstein, 1970; Bianco et al., 2008). Afterward, Caplan (1991) named them as mesenchymal stem cells (here, called mesenchymal stromal cells–MSCs) and proposed their use in regenerative medicine. In the bone marrow, the percentage of MSCc is estimated to be 0.001 to 0.01% of the total mononuclear cells. Because of their scarcity, alternative sources have been described, although bone marrow remains as the main source of MSCs (Nancarrow-Lei et al., 2017). Adipose tissue is a very promising source because it contains a large number of MSCs that are relatively easy to harvest with minimal discomfort and risk for donors (Zuk et al., 2001). The protocols used to harvest and culture MSCs from either bone marrow (BM-MSCs) or adipose tissue (AT-MSCs), may vary among different species or even among different strains of the same species. The most commonly used methods for obtaining MCSs involve using flow cytometry (Schrepfer et al., 2007), multipotent adult progenitor cell media (Harting et al., 2008), the ficoll-paque gradient centrifugation method (Pierini et al., 2012), and immunomagnetic beads (Wadajkar et al., 2014). Here, we describe cost-efficient protocols that are relatively easy and fast to perform and can be used to obtain cell populations rich in MSCs from bone marrow and adipose tissues. These protocols can be used to study several cellular and molecular aspects of MSCs, such as their proliferation, differentiation, and signaling pathways (Abuna et al., 2016; Fideles et al., 2019), the biological effects of growth factors and drugs on MSCs (Oliveira et al., 2012; Zhang et al., 2017), the interactions between MSCs and natural or synthetic biomaterials (Hu et al., 2018; Lopes et al., 2019), and the application of MSCs in regenerative medicine strategies (Almeida et al., 2019; Freitas et al., 2019).
