Cover: Immunofluorescence image showing a section of an intraductal adenoma with stroma within a prostate carcinoma of a 30-week-old TRAMP mouse carrying an Acta2-CreER transgene and R26LSL-tdTomato/+ reporter given tamoxifen at 4 weeks. Red indicates tdTomato+ cells derived from Acta2-expressing cells at 4 weeks, green indicates cells expressing ACTA2+ (smooth muscle cells), blue indicates DAPI staining of nuclei. As described in the article by Yang et al. on page 39, Acta2-expressing cells of the smooth muscle-lineage expand not only in the smooth muscle layers, but also invade into intraductal stromal space between epithelium folds and become cancer reactive stroma. Thus, smooth muscle lineage is a cell-of-origin for intraductal cancer reactive stroma in TRAMP.

REVIEW
3D bioprinting: improving in vitro models of metastasis with heterogeneous tumor microenvironments
Summary: Here, Albritton and Miller discuss recent 3D bioprinting advances that can be used to produce heterogeneous tumor microenvironments for improved physical modeling of cancer metastasis.
RESEARCH ARTICLES
A novel brain tumour model in zebrafish reveals the role of YAP activation in MAPK- and PI3K-induced malignant growth
Editors' choice: A new brain tumour model in zebrafish allows simultaneous analysis of malignant tumours and heterotopias, suggesting that both lesions originate from similar events, with Yap1 as a driving force in tumour development.
Prenatal ethanol exposure in mice phenocopies Cdon mutation by impeding Shh function in the etiology of optic nerve hypoplasia
Summary: In utero exposure to ethanol causes defects in optic nerve formation by interfering with Shh signaling activity in the growth and differentiation of retinal progenitor cells in the developing mouse eye.
Stromal hedgehog signaling maintains smooth muscle and hampers micro-invasive prostate cancer
Summary: New insights are provided into the role of hedgehog signaling in maintaining prostate smooth muscle and place hedgehog as a candidate pathway of therapeutic value for treating individuals with prostate cancer.
S113R mutation in SLC33A1 leads to neurodegeneration and augmented BMP signaling in a mouse model
Summary: Slc33a1wt/mut knock-in mice with a S113R mutation and exhibiting hereditary spastic paraplegia-related phenotypes show that SLC33A1 negatively regulates BMP signaling and axonal regeneration.
RESOURCE ARTICLE
Standardized echocardiographic assessment of cardiac function in normal adult zebrafish and heart disease models
Summary: Standardization of zebrafish echocardiography provides insights into cardiac physiology in normal and diseased states, with application for functional studies in zebrafish models of heart disease.
