Our research goes beyond the mouth. Understanding how the entire head and face forms, we can repair damage, regenerate cells and unravel the causes of diseases. We are part of the Faculty of Dentistry, Oral & Craniofacial Sciences at King's College London
Congratulations to Dr Marta Perera from the Tucker lab, who won Best Postdoctoral Researcher Presentation at the 38th Head Group Meeting hosted @ucl.ac.uk
She discussed her work which uses spatial transcriptomics to explore the development of the embryonic salivary gland.
Congratulations Marta!

This work could provide framework for understanding the mechanisms underlying microtia, a birth defect affecting pinna morphology and often associated with hearing loss in individuals with congenital disorders.
Congratulations to all authors!

This interaction is mediated through FGFs secreted by the muscle, which signal to the developing cartilage, where they upregulate BMP4 expression. BMP4, in turn, induces the expression of Sox9, a master transcription factor for cartilage differentiation.

In this paper that the authors show the role of the auricular muscle in regulating pinna development. The muscle (mesoderm-derived) instructs differentiation of the cartilage (derived from neural crest).

Immunofluorescence image of the forming mouse pinna at E14.5. 12-101 (muscle marker) is in red, Sox9 (cartilage and Schwann cell precursor marker) is in green and DAPI nuclear stain is in blue. Note the close proximity of the muscle and pinna cartilage cells.

Using this approach, the authors predict and experimentally validate a novel driver of placode development, the transcription factor FOXK2.

Integrating this new data with previously published scRNA-seq from the lab, the paper explores dynamics of chromatin accessibility across emerging cell types and infers a gene regulatory network controlling the specification of cranial placodes.

This work led by Eva Hamrud presents a single cell ATAC-seq atlas of the developing chick ectoderm across stages that coincides with the emergence of major cell lineages from the neural plate border.

In the paper authors show that the fibrocartilage of the murine glenoid fossa and condyle of the TMJ are shown to form at distinct times with distinct molecular identities. Changes in the condyle during disease lead to remodelling of the fossa to maintain joint alignment.

First author Dr. Julie Yue Yuan showed MMP9 inhibition acted on inflammatory cells to promote a more effective migratory response of muscle stem cells, resulting in improved muscle repair in telomerase mutants.

It's Halloween in CCRB! Today we held our traditional Pumpkin Carving Competition, and it was a very competitive one!
Congratulations to @karenjliu.bsky.social 's lab for the win!
Can you guess which was the winner?
This review highlights emerging research that has located progenitor cells in and around the superficial layers of the condyle of the TMJ that can contribute to growth and homeostasis, providing potential targets for regenerative therapies.

The temporomandibular joint (TMJ) is a crucial part of our daily lives, playing a role in mastication and communication. Temporomandibular disorders (TMDs) are highly prevalent ( 34%-38% of world population), but therapies are challenging due to the limited self-repair capability of the TMJ.

CCRB paper alert!
Most snakes can open their mouths so wide they can consume food that is much larger than their own head. This is partly due to their ‘free’ mandibular symphysis, found to be both bone and cartilage-free. So, how ‘free’ is that symphyseal gap?

A great way to end the week with some evo devo! A one day meeting hosted by @qmul.bsky.social #UKEvoDevo @biologists.bsky.social @chemamd.bsky.social
As the sun sets over beautiful bustling Liverpool we reflect back on the great week we've had at the #biologists100 and how we were in truly great company with @biologists.bsky.social #liverpool #scouse #development #experimentalbiology #cellbiology
Topping off a fantastic #biologists100 conference with a stimulating panel discussion @biologists.bsky.social
Last night's #biologists100 gala dinner was trés fancy! @biologists.bsky.social you clean up nicely 💅💃 #stgeorgeshall #liverpool #galadinner
Day 2 of #biologists100 starts with two fantastic climate change talks from Hans-Otto Portner and Jane Francis. Both with the message that we need to act now! @biologists.bsky.social @ipcc.bsky.social @bas.ac.uk
We're here in sunny seaside Liverpool for the @biologists.bsky.social 100 year anniversary meeting #100biologists
