Our results show that when added to cultures in the absence of recombinant stimulatory cytokines, neither molecule had any effect. In contrast, when added in the presence of hematopoietic cytokines, UM171 and SR1 had significant stimulatory effects on cell proliferation and expansion in cultures of LIN⁻ and CD34⁺ cells. No significant effects were observed in cultures of MNCs. The effects of both molecules were more pronounced in cultures with the highest proportion of CD34⁺ cells, and the greatest effects were observed when both molecules were added in combination. In the absence of small molecules, cell numbers reached a peak by days 25–30, and then declined; whereas in the presence of UM171 or/and SR1 cell numbers were sustained up to day 45 of culture. Our results indicate that besides CD34⁺ cells, LIN⁻ cells could also be used as input cells in clinically-oriented expansion protocols, and that using both molecules simultaneously would be a better approach than using only one of them.</div></div>","PeriodicalId":8972,"journal":{"name":"Blood Cells Molecules and Diseases","volume":"110 ","pages":"Article 102895"},"PeriodicalIF":2.1,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142280115","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We evaluated whether growth hormone (GH) is an extracellular stimulator that participates in the signal transduction of GATAs, focusing on GATA1 expression in hematopoietic cell lineages. We used a reporter assay, RT-PCR, real-time quantitative PCR, and western blotting to evaluate GH-induced expression of GATA1 and GATA2 in the human erythroleukemic cell line K562 and the non-erythroid cell line U937. GATA1 expression in these hematopoietic cell lines increased at the transcriptional and protein levels in the presence of GH, and was inhibited by a STAT5 specific inhibitor. Cells transfected with activated STAT5B showed increased expression of GATA1. We identified functional STAT5B consensus sequences as binding site-158 bp from the transcription starting site in the GATA1 promoter region.

The group met at the Institute for the first time in October 1972. After the first meeting, Bessis published the articles describing the presentations in the &lt;em&gt;Nouvelle Revue d'Hématologie Française&lt;/em&gt;, France's principal journal for articles on the science and practice of hematology of which he was the editor. The refusal of the &lt;em&gt;Nouvelle Revue d'Hématologie Française&lt;/em&gt; to continue publishing the papers from the meeting of the blood club in English prompted Bessis to start a new journal, &lt;em&gt;Blood Cells&lt;/em&gt;, in 1975. &lt;em&gt;Blood Cells&lt;/em&gt;, also, began to accept individual submitted papers unrelated to the blood club meeting and, thus, it evolved into a standard journal. A decade later, when Bessis became ill, he asked Brian Bull, a hematopathologist and professor at Loma Linda University School of Medicine in California to assume the position as the second editor-in-chief. He and Bessis had become scientific collaborators and good friends in the preceding years. In 1995, Ernest Beutler, Chair of Molecular and Experimental Medicine at Scripps Research Institute, assumed the editor-in-chief position and transformed the &lt;em&gt;Journal&lt;/em&gt; by making three consequential changes. He expanded its title to &lt;em&gt;Blood Cells, Molecules and Diseases&lt;/em&gt;, converted its editorial board to past presidents of the American Society of Hematology plus a few additional experimental hematologists of note, a few from abroad, and he converted the &lt;em&gt;Journal&lt;/em&gt; to a digital format, hosted on the Scripps Research Institute server. The &lt;em&gt;Journal&lt;/em&gt; was the first published solely in a digital format. It, subsequently, was bought by Academic Press, then Harcourt and, then, by Elsevier. The next three editors-in-chief were (i) Marshall A. Lichtman, then Professor of Medicine (Hematology) and of Biochemistry and Biophysics and former Dean of the School of Medicine and Dentistry at the University of Rochester Medical Center, editor from 2000 to 2013, (ii) Mohandas Narla, then Vice President for Research and Director of The Laboratory of Red Cell Physiology at the New York Blood Center, editor from 2014 to 2021 and (iii) Lionel Blanc, Professor of Molecular Medicine and Pediatrics, Center for Autoimmune, Musculoskeletal and Hematopoietic Diseases, Institute of Molecular Medicine, The Feinstein Institutes for Medical Research and the Les Nelkin Professor of Pediatric Oncology Donald and Barbara Zucker School of Medicine at Hofstra-Northwell from 2022 to the present.
