Abstrakt: Macrophages derived from human monocytic leukemia THP-1 cell line are often used as the alternative of human primary macrophage. However, the polarization method of THP-1 to macrophages varies between different laboratories, which may unknowingly affect the relevance of research output across research groups. In this regard, a systematic search was developed in Pubmed, BioOne, Scopus, and Science Direct to identify articles focusing on THP-1 polarization into M1 and M2 macrophages. All selected articles were read and discussed by two independent reviewers. The selection process was based on selected keywords on the title, abstract and full-text level. A total of 85 articles were selected and categorized based on the field of studies, method of THP-1 differentiation, and markers or genes expressed upon differentiation. THP-1 derived macrophages were mainly used together with primary monocyte-derived macrophages in cellular inflammation studies, while it was commonly employed alone in cancer research. THP-1 derived macrophages are also of paramount importance in biomaterials studies to prevent unfavorable immune responses in-vivo. We explored various methods of THP-1 differentiation and suggested several common genes encountered to characterize M1 and M2 macrophages differentiated from THP-1. The systematic review highlights the relevance of using THP-1 derived macrophage as a useful alternative to primary macrophage. Although it is not possible to derive a standard method of THP-1 polarization into M1 and M2 macrophages from this review, it may lead researchers to obtain reproducible polarization protocol based on commonly used stimulants and markers of differentiation.
