Dr Creemers studied one year Biology in Utrecht and subsequently Biomedical Sciences in Leiden. After obtaining her master’s degree, she has worked in several research areas, including spermatogenic stem cells, (periodontal) ligament, tendon and bone. Since 2005 her focus is on cartilage and intervertebral disc (IVD) research with a special interest in biomaterials-based local delivery approaches for regeneration and treatment of inflammation. She has in the past years been involved in several projects on local drug delivery, including BMM IDiDAS (PI) targeting disc degeneration and BMM-OAcontrol on osteoarthritis.


In the ongoing projects, biomaterial-based delivery for inhibition of degeneration and stimulation of regeneration of the IVD and articular cartilage includes small molecules, proteins, peptides and nucleic acids, with delivery of anti-inflammatory mediators in osteoarthritis and intervertebral disc degeneration most close to clinical translation. Carriers vary from hydrogels and microparticles to nanoparticles. Research is done both in vitro and in in vivo models, ranging from rat to large animals, the latter in close collaboration with the dept of Companion Animals at the Fac Veterinary Medicine. Readouts include regular microscopy and biochemistry, pharmacokinetics, mass spectrometry imaging and in vivo imaging.
