Abstract

Heterozygous variants in SOX10 cause congenital syndromes affecting pigmentation, digestion, hearing, and neural development, primarily attributable to failed differentiation or loss of non-skeletal neural crest derivatives. We report here an additional, previously undescribed requirement for Sox10 in bone mineralization. Neither crest- nor mesoderm-derived bones initiate mineralization on time in zebrafish sox10 mutants, despite normal osteoblast differentiation and matrix production. Mutants are deficient in the Trpv6+ ionocytes that take up calcium from the environment, resulting in severe calcium deficiency. As these ionocytes derive from ectoderm, not crest, we hypothesized that the primary defect resides in a separate organ that systemically regulates ionocyte numbers. RNA sequencing revealed significantly elevated stanniocalcin (Stc1a), an anti-hypercalcemic hormone, in sox10 mutants. Stc1a inhibits calcium uptake in fish by repressing trpv6 expression and Trpv6+ ionocyte proliferation. Epistasis assays confirm excess Stc1a as the proximate cause of the calcium deficit. The pronephros-derived glands that synthesize Stc1a interact with sox10+ cells, but these cells are missing in mutants. We conclude that sox10+ crest-derived cells non-autonomously limit Stc1a production to allow the inaugural wave of calcium uptake necessary to initiate bone mineralization.

Sox10是骨矿化系统启动所必需的。
SOX10的杂合变异可导致先天性综合征,影响色素沉着、消化、听力和神经发育,主要是由于分化失败或非骨骼神经嵴衍生物的丢失。我们在此报告了骨矿化对Sox10的额外新要求。尽管正常的成骨细胞分化和基质生成,斑马鱼sox10突变体的嵴骨和中胚层骨都不能按时启动矿化。突变体缺乏从环境中吸收钙的Trpv6+离子细胞,导致严重的缺钙。由于这些离子细胞来自外胚层,而不是嵴,我们假设主要缺陷存在于系统调节离子细胞数量的单独器官中。RNAseq显示,在sox10突变体中,Stc1a(一种抗高钙激素)显著升高。Stc1a通过抑制trpv6表达和trpv6 +离子细胞增殖抑制鱼类钙摄取。上位分析证实过量的Stc1a是钙缺乏症的直接原因。原肾源性腺体合成Stc1a与sox10+细胞相互作用,但这些细胞在突变体中缺失。我们得出结论,sox10+嵴来源的细胞非自主地限制Stc1a的产生,以允许启动骨矿化所需的钙摄取的起始波。

期刊介绍: Development’s scope covers all aspects of plant and animal development, including stem cell biology and regeneration. The single most important criterion for acceptance in Development is scientific excellence. Research papers (articles and reports) should therefore pose and test a significant hypothesis or address a significant question, and should provide novel perspectives that advance our understanding of development. We also encourage submission of papers that use computational methods or mathematical models to obtain significant new insights into developmental biology topics. Manuscripts that are descriptive in nature will be considered only when they lay important groundwork for a field and/or provide novel resources for understanding developmental processes of broad interest to the community. Development includes a Techniques and Resources section for the publication of new methods, datasets, and other types of resources. Papers describing new techniques should include a proof-of-principle demonstration that the technique is valuable to the developmental biology community; they need not include in-depth follow-up analysis. The technique must be described in sufficient detail to be easily replicated by other investigators. Development will also consider protocol-type papers of exceptional interest to the community. We welcome submission of Resource papers, for example those reporting new databases, systems-level datasets, or genetic resources of major value to the developmental biology community. For all papers, the data or resource described must be made available to the community with minimal restrictions upon publication. To aid navigability, Development has dedicated sections of the journal to stem cells & regeneration and to human development. The criteria for acceptance into these sections is identical to those outlined above. Authors and editors are encouraged to nominate appropriate manuscripts for inclusion in one of these sections.
