To read the full abstract: Development 2017;144:3879-3893Regenerative medicine techniques are being widely investigated for organs without regenerative capacity, such as lung. Whether pluripotent stem cell derived thyroid organoids will be used in the future as a regenerative medicine approach to treat hypothyroidism is unclear. In the context of an easily available, very cheap and non-in...

To read the full abstract: J Clin Invest 2018;128:1913-1918Two rare genetic forms of vitamin D–dependent rickets exist: VDDR-1 caused by mutations in the genes encoding either the renal 1-α hydroxylase (CYP27B1: VDDR-1A) or the hepatic 25-hydroxylase (CYP2R1: VDDR-1B) and VDDR-2 caused by mutations in the vitamin D receptor signalling due to mutations in the gene encoding the ...

Brief summary: Exposure to endocrine disrupting chemicals may have adverse effects on humans. Tissue specific organoids are a helpful model to study organ specific impact of compounds alone or in combination, at different doses and during different stages of tissue development (1). While such organoid models have been developed for different tissues, such models were lacking to study differentiated thyroid follicles and thyroid tissue during development and differentiation.</p...

In Brief: The study established a novel rat model with a clinically relevant PLS3 mutation, which replicates the osteoporotic phenotype of early-onset PLS3-related osteoporosis. The findings suggest that treatment with alendronate or teriparatide improves bone mass and microarchitecture, suggesting their potential as effective treatments for early-onset osteoporosis caused by PLS3 mutations.Commentary: This study is an essentia...
