A role for connective tissue growth factor (CTGF) in reproductive function has been suggested from recent studies in the pig. To extend these findings, we have analyzed the immunohistochemical localization of CTGF during the estrous cycle and early pregnancy in mice. During the diestrous and early proestrous stages, CTGF was localized at high levels to both luminal and glandular uterine epithelial cells and at much lower levels in the stroma or myometrium. Epithelial expression of CTGF was considerably reduced at estrus. On Days 1.5-3.5 of pregnancy, CTGF was localized mainly to the uterine epithelial cells, which showed a substantially reduced level of CTGF on Day 4.5. On Days 5.5 and 6.5, CTGF was present at high levels in uterine decidual cells. CTGF was detected in the trophectoderm and inner cell mass of the preimplantation embryo on Day 4.5 and became preferentially localized to embryonic endoderm and mesoderm on Days 5.5-6.5. Multiple mass forms of CTGF (Mr 14 000-38 000) were present in endometrial extracts and uterine luminal flushings. Collectively, these data support a role for CTGF in uterine cell growth, migration, adhesion, and extracellular matrix production during the estrous cycle and early pregnancy, as well as in early development of the embryo.

Introduction The social worker (SW) role in the Hemophilia Treatment Center (HTC) is complex and broad, providing direct support, spanning across micro, mezzo and macro levels of care. Aim Research demonstrates discrepancy between actual and ideal SW roles among the HTC SW community. Soliciting perceptions from HTC staff about the SW role can provide a deeper understanding of this discrepancy and improve collaboration amongst care team members in meeting the psychosocial needs of HTC patients. Methods Funded by the National Hemophilia Foundation (NHF), a national online survey was conducted in 2020 to determine the views and attitudes of what the SW role is by HTC staff. Separate surveys were emailed to active HTC SWs and staff to collect anonymous data. Demographics of SWs gathered included age, education, years of practice, full time equivalent (FTE) status, and caseload. All disciplines were asked questions about perceptions, barriers, and potential ways to enhance and strengthen the SW role within HTCs. Results Results demonstrated that subcategory‐oriented questions (40 in total) and qualitative responses highlighted diverse viewpoints and offered clarity about these differences. Conclusion Findings indicated most HTC staff value the multi‐faceted role of SW at their centres, and both groups identified time, limited resources, and role confusion as barriers to utilizing SW services. Outcomes will inform the development of a “standards of practice” tool that will provide education for HTC staff, patients, and families, and serve as an empowerment tool for SW to highlight their skillset and define their role.
