The percentages of T lymphocytes (E-rosetting and T3+ cells) were lower in cord blood than in peripheral blood (PB) from adults, while the percentage and absolute number of T6+ cells were higher in cord blood. As the sum of T4+ and T8+ cells exceeded the values of E-rosetting lymphocytes in cord blood, we suggest that immature lymphocytes with the phenotype of \u2018common\u2019 thymocytes (T6+, T4+, T8+) are present in cord blood of full-term newborns. Higher percentage and absolute number of B lymphocytes were detected in cord blood. More than 50% of B cells in cord blood formed rosettes with mouse erythrocytes, a surface marker of functional immaturity. Finally, cells bearing receptors for IgG-Fc fragments or C3 and expressing Ia-like and Ml antigens were uniformly increased in cord blood, suggesting higher percentages of cells of the monocytic lineage.<\/jats:p>","DOI":"10.1159\/000241731","type":"journal-article","created":{"date-parts":[[2009,9,25]],"date-time":"2009-09-25T09:42:34Z","timestamp":1253871754000},"page":"303-308","source":"Crossref","is-referenced-by-count":23,"title":["Phenotypic Immaturity of T and B Lymphocytes in Cord Blood of Full-Term Normal Neonates"],"prefix":"10.1159","author":[{"given":"Giacomo","family":"Lucivero","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adriana","family":"Dell\u2019Osso","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aldo","family":"Iannone","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luigi","family":"Selvaggi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Salvatore","family":"Antonaci","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Silvio","family":"Bettocchi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lorenzo","family":"Bonomo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,9,17]]},"container-title":["Biology of the Neonate"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/241731","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000241731","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T22:17:10Z","timestamp":1777673830000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000241731"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,9,17]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000241731","archive":["Portico"],"relation":{},"ISSN":["0006-3126","1421-9727"],"issn-type":[{"value":"0006-3126","type":"print"},{"value":"1421-9727","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,9,17]]}}}
