New release: Spatial Transcriptomics of Mouse CFA-induced TMJ arthritis
March 4th, 2026
Spatial transcriptomics of the mouse temporomandibular joint (TMJ) using seqFISH, from the dataset Spatial Transcriptomics of Mouse CFA-induced TMJ arthritis
PI: Jian-Fu Chen (University of Southern California)
Description:
Complete Freund’s Adjuvant (CFA)-induced Temporomandibular joint (TMJ) arthritis remodels the cartilage, subchondral bone, and synovial tissue with diverse cell changes. The functional importance of the anatomical organization of TMJ cell types and cellular microenvironment in painful arthritis remains largely unknown. Here, we applied seqFISH (sequential Fluorescence In Situ Hybridization) spatial transcriptomicsto examine the adult mouse TMJ. We uncovered new cell types and comprehensively mapped anatomical locations of diverse cell types with distinct neighborhoods, revealed arthritis-induced cell number and cell status changes, and discovered microenvironment remodeling of fibroblast-immune cells, which are confirmed in patient synovial tissues. Functional and mechanistic studies showed that macrophage-specific knockout of mouse Igf1 promotes its immune activation and upregulates Il33 in adjacent synovial fibroblasts, resulting in inflammatory fibroblast expansion. In turn, fibroblast-specific deletion of Il33 alleviates inflammatory macrophages and inflammation, leading to pain mitigation. Thus, spatial transcriptomics maps diverse cell types in TMJ and reveals a remodeling of synovial fibroblast-immune microenvironment via the Igf1-Il33 axis, which drives arthritis pain with therapeutic potentials.

New release: MicroCT analysis of ameloblast specific Smad4 conditional knockout mice and Ambn-IRESCre mouse models
February 11th, 2026
Mutant sample from the dataset MicroCT analysis of ameloblast specific Smad4 conditional knockout mice
Description:
Michael Paine’s lab (University of Southern California) developed a novel ameloblastin driven Cre-recombinase mouse line (Ambn-IRESCre MMRRC Strain #067446-JAX; RRID:MMRRC_067446-JAX) with Cre expression limited to enamel forming cells called ameloblasts. This is a significant advance from the current Cre mouse lines used in conditional gene silencing to study enamel formation. We used this Ambn-IRESCre line to knockdown the transcription factor Smad4 specifically in ameloblasts and achieved an extreme pathological phenotype limited to tooth enamel with no effects on the physiological functions of Smad4. These data highlight the significance of the Ambn-IRESCre mouse model for future studies defining gene functions during enamel formation.

This data is part of EnamelBase, a community resource providing validated genetic mouse tools and multi-scale data to study gene expression, structure, and mechanical properties of developing and mature tooth enamel.

We hope you’ll join us in Arlington this May and help shape the conversation around data reuse and AI-ready biomedical research.
Register for the 2026 FaceBase Community Forum – May 4–5 in Arlington, VA
February 4th, 2026
We’re excited to announce that the 2026 FaceBase Community Forum will take place May 4–5, 2026, at the University of Southern California/Information Sciences Institute East Office in Arlington, VA. This two-day, in-person event will bring together researchers, clinicians, data scientists, contributors, and trainees from across dental, oral, and craniofacial (DOC) science as well as related areas such as the ear, eye, and other craniofacial-associated systems.
This year’s annual meeting will highlight new tools, datasets, and research supported by FaceBase, with expanded discussions on AI-ready biomedical data and how structured metadata, packaging, and standards within the platform enable machine learning, multimodal integration, and new scientific insights.
Sessions will include invited talks, panel discussions, demonstrations, poster presentations, and community-driven conversations with the FaceBase team. It’s an opportunity to learn, collaborate, and help shape the future of the FaceBase resource.
