Its impact on pharmacological properties of many drugs has been extensively studied over decades. Here, we focus on its interaction with the following mobilizing agents: Granulocyte-colony stimulating factor (G-CSF) and AMD3100, where such analyses are lacking. These compounds are widely used for hematopoietic stem cell mobilization of healthy donors or patients. Using albumin-deficient (Alb\u2212\/\u2212) mice, we studied the contribution of albumin to mobilization outcomes. Mobilization with the bicyclam CXCR4 antagonist AMD3100 was attenuated in Alb\u2212\/\u2212 mice compared to wild-type littermates. By contrast, mobilization with recombinant human G-CSF (rhG-CSF), administered twice daily over a five-day course, was significantly increased in Alb\u2212\/\u2212 mice. In terms of a mechanism, we show that rhG-CSF bioavailability in the bone marrow is significantly improved in Alb\u2212\/\u2212 mice, compared to wild-type (WT) littermates, where rhG-CSF levels dramatically drop within a few hours of the injection. These observations likely explain the favorable mobilization outcomes with split-dose versus single-dose administration of rhG-CSF to healthy donors.<\/jats:p>","DOI":"10.3390\/cells9010004","type":"journal-article","created":{"date-parts":[[2019,12,23]],"date-time":"2019-12-23T03:23:12Z","timestamp":1577071392000},"page":"4","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Albumin Modifies Responses to Hematopoietic Stem Cell Mobilizing Agents in Mice"],"prefix":"10.3390","volume":"9","author":[{"given":"Eva","family":"Danner","sequence":"first","affiliation":[{"name":"German Red Cross Blood Donor Service Baden-Wuerttemberg-Hesse, 60528 Frankfurt, Germany"},{"name":"Faculty of Biological Sciences, Goethe University, 60438 Frankfurt, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Halvard","family":"Bonig","sequence":"additional","affiliation":[{"name":"German Red Cross Blood Donor Service Baden-Wuerttemberg-Hesse, 60528 Frankfurt, Germany"},{"name":"Goethe University Medical School, Institute for Transfusion Medicine and Immunohematology, 60528 Frankfurt, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8434-6492","authenticated-orcid":false,"given":"Eliza","family":"Wiercinska","sequence":"additional","affiliation":[{"name":"German Red Cross Blood Donor Service Baden-Wuerttemberg-Hesse, 60528 Frankfurt, Germany"},{"name":"Goethe University Medical School, Institute for Transfusion Medicine and Immunohematology, 60528 Frankfurt, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,12,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"209","DOI":"10.1016\/j.mam.2011.12.002","article-title":"Human serum albumin: From bench to bedside","volume":"33","author":"Fanali","year":"2012","journal-title":"Mol.
