These cellular populations alter dynamically during aging or as a response to pathophysiology such as obesity. Changes in the various inflammatory cells are associated with metabolic complications and the development of insulin resistance, indicating that immune cells crosstalk with the adipocytes. Therefore, a study of the cell populations in the adipose tissue and the extracellular matrix maintaining the tissue niche is important for the knowledge on the regulatory state of the organ. We used a combination of methods to study various parameters to identify the composition of the resident cells in the adipose tissue and evaluate their profile. We analyzed the tissue structure and cells based on histology, immune fluorescence staining, and flow cytometry of cells present in the tissue in vivo and these markers\u2019 expression in vitro. Any shift in cells\u2019 composition influences self-renewal of the mesenchymal progenitors, and other cells affect the functionality of adipogenesis.<\/jats:p>","DOI":"10.3390\/biom11121906","type":"journal-article","created":{"date-parts":[[2021,12,19]],"date-time":"2021-12-19T20:41:55Z","timestamp":1639946515000},"page":"1906","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Exploring the Cell Stemness and the Complexity of the Adipose Tissue Niche"],"prefix":"10.3390","volume":"11","author":[{"given":"Nadav","family":"Kislev","sequence":"first","affiliation":[{"name":"Department of Cell and Developmental Biology, Sackler School of Medicine, Tel Aviv University, Tel Aviv 6997801, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8600-9481","authenticated-orcid":false,"given":"Roza","family":"Izgilov","sequence":"additional","affiliation":[{"name":"Department of Cell and Developmental Biology, Sackler School of Medicine, Tel Aviv University, Tel Aviv 6997801, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1776-1434","authenticated-orcid":false,"given":"Raizel","family":"Adler","sequence":"additional","affiliation":[{"name":"Department of Cell and Developmental Biology, Sackler School of Medicine, Tel Aviv University, Tel Aviv 6997801, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dafna","family":"Benayahu","sequence":"additional","affiliation":[{"name":"Department of Cell and Developmental Biology, Sackler School of Medicine, Tel Aviv University, Tel Aviv 6997801, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,12,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2548","DOI":"10.1210\/jc.2004-0395","article-title":"Adipose Tissue as an Endocrine Organ","volume":"89","author":"Kershaw","year":"2004","journal-title":"J.
