Aurélie‘s paper (on which Yuming and Rebecca are also authors) entitled “Short-term foetal immobility temporally and progressively affects chick spinal curvature and anatomy and rib development” has been published in eCM (European Cells and Materials). The paper describes how a very short period of paralysis during prenatal development can have severe and lasting effects on development of the spine and ribs, as summarised in the graphical abstract. This work has consequences for understanding congenital scoliosis, for which a change or reduction in fetal movements could be an important factor. The project was funded by the Leverhulme Trust and was a collaboration with Prof James Iatridis in the Icahn School of Medicine at Mount Sinai, New York, USA. View the paper for free here.
The group celebrated an “eco-friendly” Secret Santa this year, with homemade or edible gifts being the rule. Some very tasty treats were shared, but the best gift was definitely the “mini Kaushik” that Yuming made, complete with computer and signature water bottle. Kudos Yuming! The secret santa fun was followed by a very nice Indian meal in South Kensington. Happy Christmas from all the Nowlan group!
The entire group (including alumnus Stefaan) traveled to Dublin for the 2018 World Congress of Biomechanics in July. Between us, we presented seven talks and one poster, as listed below. Aurélie and Kaushik also presented abstracts based on their PhD projects. Niamh was Co-Chair for the ‘Emerging Areas’ Track and a Session Chair for the “Biomechanics of Musculoskeletal Development” session. A particular highlight of the meeting was Stefaan giving a plenary lecture to mark the Perren Award.
Aurélie: Critical timings of fetal mobility for spine and rib development
Cristian: Frequency and duration of mechanical stimulation influence mineralisation of developing chick limbs cultured in vitro
Devi: Timing of movement is essential for cavitation and morphogenesis of the developing chick hip joint
Kaushik: Musculoskeletal forces and prenatal skeletogenesis: a murine model
Niamh: Directing cartilage growth in vitro: learning from developmental biology
Saima: Characterisation of collagen distribution in the prenatal forelimb using immunofluorescence and high-resolution microscopy
Stefaan: Biomechanical stimulation of the fetal skeleton linked to risk factors for developmental dysplasia of the hip
Vivien: Shoulder joint shape is rescued as development progresses when limb musculature is absent in the murine embryo

Kaushik has been awarded a Marie Skłodowska-Curie Individual Fellowship, to start in September 2018. Kaushik’s fellowship is entitled “Mechanobiology of Proprioceptive Regulation of Bone and Joint Morphogenesis” and will involve collaboration between the Developmental Biomechanics group at Imperial College London, and the Zelzer Lab at the Weizmann Institute in Israel. Congratulations Kaushik!
Stefaan’s final and Perren Award winning paper from his postdoc in the Developmental Biomechanics has been published online in the Journal of Biomechanics. In the paper, the effects of different risk factors for hip dysplasia (such as fetal breech position, first born babies and oligohydramnios (reduced amniotic fluid)) on fetal kicks and the stresses and strains in their hip joints are quantified. Kick force, stress and strain were found to be significantly lower in cases of breech position and oligohydramnios. Similarly, firstborn fetuses were found to generate significantly lower kick forces than non-firstborns.
Congratulations to Aurélie and Cristian who have received travel awards from the European Society of Biomechanics for the World Congress of Biomechanics in Dublin in July! Aurélie will present her work on ‘Critical timings of fetal mobility for spine and rib development’ and Cristian will present work entitled ‘Frequency and duration of mechanical stimulation influence mineralisation of developing chick limbs cultured in vitro’. Well done!
Congratulations to Stefaan and co-authors whose paper entitled “Altered Biomechanical Stimulation of the Developing Hip Joint in Presence of Hip Dysplasia Risk Factors” (soon to be published in the Journal of Biomechanics) has been awarded the 2018 S.M. Perren Award by the European Society of Biomechanics! Stefaan will present a plenary lecture of the World Congress of Biomechanics in Dublin, Ireland in July.
Congratulations to Saima who has been awarded, not one, but two travel awards/grants for conference travel this summer. Saima received the British Society of Matrix Biology FECTS bursary to attend the Matrix Biology Europe conference (worth approx £1,000) and the the Physiological Society Travel Grant, worth up to £700, to attend the 8th World Congress of Biomechanics, Dublin: Well done Saima!
Our paper on developing a new type of sensor for fetal movements has been published in PLoS One! The paper describes how acoustic sensors are combined with accelerometers for the first time. The sensor was able to detect and identify the short, rigorous ‘startle’ movements of the fetus. Further development is ongoing, but this is an important first step! The work builds on a patent held by the several of the authors, including Niamh.
