Currently, supplemental cation-doping is suggested as a powerful path to boost biofunctionality, however, there is still a lack of knowledge on the structural role of such substituents in BCPs, which in turn, could influence the intensity and extent of the biological effects. In this work, pure and Mg- and Sr-doped BCP scaffolds were fabricated by robocasting from hydrothermally synthesized powders, and then preliminarily tested in vitro and thoroughly investigated physically and chemically. Collectively, the osteoblast cell culture assays indicated that all types of BCP scaffolds (pure, Sr- or Sr\u2013Mg-doped) delivered in vitro performances similar to the biological control, with emphasis on the Sr\u2013Mg-doped ones. An important result was that double Mg\u2013Sr doping obtained the ceramic with the highest \u03b2-tricalcium phosphate (\u03b2-TCP)\/hydroxyapatite mass concentration ratio of ~1.8. Remarkably, Mg and Sr were found to be predominantly incorporated in the \u03b2-TCP lattice. These findings could be important for the future development of BCP-based bone graft substitutes since the higher dissolution rate of \u03b2-TCP enables an easier release of the therapeutic ions. This may pave the road toward medical devices with more predictable in vivo performance.<\/jats:p>","DOI":"10.3390\/jfb13030123","type":"journal-article","created":{"date-parts":[[2022,8,24]],"date-time":"2022-08-24T00:22:48Z","timestamp":1661300568000},"page":"123","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Sr and Mg Doped Bi-Phasic Calcium Phosphate Macroporous Bone Graft Substitutes Fabricated by Robocasting: A Structural and Cytocompatibility Assessment"],"prefix":"10.3390","volume":"13","author":[{"given":"Cristina","family":"Besleaga","sequence":"first","affiliation":[{"name":"National Institute of Materials Physics, RO-077125 Magurele, Romania"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6580-7273","authenticated-orcid":false,"given":"Bo","family":"Nan","sequence":"additional","affiliation":[{"name":"Department of Materials and Ceramics Engineering, CICECO, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"given":"Adrian-Claudiu","family":"Popa","sequence":"additional","affiliation":[{"name":"National Institute of Materials Physics, RO-077125 Magurele, Romania"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5962-4836","authenticated-orcid":false,"given":"Liliana Marinela","family":"Balescu","sequence":"additional","affiliation":[{"name":"National Institute of Materials Physics, RO-077125 Magurele, Romania"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0612-590X","authenticated-orcid":false,"given":"Liviu","family":"Nedelcu","sequence":"additional","affiliation":[{"name":"National Institute of Materials Physics, RO-077125 Magurele, Romania"}]},{"given":"Ana Sofia","family":"Neto","sequence":"additional","affiliation":[{"name":"Department of Materials and Ceramics Engineering, CICECO, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0187-9091","authenticated-orcid":false,"given":"Iuliana","family":"Pasuk","sequence":"additional","affiliation":[{"name":"National Institute of Materials Physics, RO-077125 Magurele, Romania"}]},{"given":"Lucia","family":"Leonat","sequence":"additional","affiliation":[{"name":"National Institute of Materials Physics, RO-077125 Magurele, Romania"}]},{"given":"Gianina","family":"Popescu-Pelin","sequence":"additional","affiliation":[{"name":"National Institute for Lasers, Plasma and Radiation Physics, RO-077125 Magurele, Romania"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7520-2809","authenticated-orcid":false,"given":"Jos\u00e9 M.
