Objectives Mesenchymal stem/stromal cells (MSCs) are a well-established cell source for cartilage engineering, but challenges remain as differentiation often results in chondrocyte hypertrophy. Chondrogenic potential also varies with MSC source and donor age. We assessed the chondrogenic potential of first-trimester and term placental MSCs and compared their response to commonly used bone marrow MSCs (BM-MSCs). Design MSCs were isolated from first-trimester and term placentae. BM-MSCs were commercially obtained. Chondrogenesis was induced by micromass culture in commercial chondrogenic media for 7, 14, or 21 days. Pellets were assessed for glycosaminoglycan (GAG) content, and types I, II, and X collagen. Gene expression was profiled using Qiagen RT2 human MSC arrays. Results At day 0, first-trimester and term MSCs expression levels of many chondrogenic genes to BM-MSC after 21 days of culture. Only first trimester MSCs showed significant changes in chondrogenic gene expression during induction compared to day 0 undifferentiated MSCs (greater BMP4, KAT2B, and reduced GDF6 expression). Additionally, first-trimester MSCs showed significantly greater expression of ABCB1 (at days 14 and 21) and BMP4 (at days 7, 14, 21) compared with term MSCs. Both first-trimester and term pellets showed increased GAG content over time and term MSCs had significantly GAG greater compared with BM-MSCs at days 7 and 14. Type II collagen was present in all pellets but unlike BM-MSCs, type I collagen was not observed in first-trimester or term MSC pellets. Conclusions These data highlight differences in BM-MSC and placental MSC chondrogenesis and demonstrate that placental MSCs may be an alternative cell source.
Background. Access to publicly funded abortion in Australia is limited, with a considerable proportion carried out by private providers. There are no nationally reported data on public abortion services, and referral pathways are poorly coordinated between hospital and primary care sectors. HealthPathways is an online system for use in primary care that provides information on referral pathways to local services. The aim of this study was to describe abortion referral pathways for each HealthPathways portal in Australia. Methods. A review of Australian HealthPathways content on abortion was undertaken between January and June 2022. For each HealthPathways portal, data were extracted on referral options to abortion services. Results. Overall, 17 out of 34 Australian HealthPathways consented to be included. Nearly half (47%) had no public services listed for surgical abortion, and 35% had no public services for medical abortion. The majority (64% for surgical abortion, 67% for medical abortion) emphasised that public services should be considered only as a last resort. There was variation in information regarding gestation-specific options, the time-critical nature of referrals, and the importance of women's own preference when deciding between medical or surgical abortion. Conclusion. Despite few remaining legal restrictions to abortion, many regions across Australia either do not have public abortion services or do not provide information about them. There is an urgent need for transparency around public abortion service availability, clear guidelines to support referral pathways, and commitment from State and Federal governments to expand the availability of accessible, no-cost abortion in Australia.
