New European Project “SmILE” Aims to Revolutionize Musculoskeletal Disease Management

SmILE develops smart implants and digital health solutions to prevent and manage musculoskeletal diseases, enhancing patient care and independence.

Lübeck, February 2025. The European project “SmILE” has been launched to provide innovative solutions for reducing the burden of musculoskeletal non-communicable diseases (MSK-NCDs) among the elderly through preventive measures and early interventions. Supported by the Horizon Europe programme and the Swiss State Secretariat for Education, Research and Innovation (SERI), this collaborative initiative brings together 25 institutions from 12 European countries with a budget of €19.9 million, plus an additional €760K from SERI, over five years.

Addressing the Challenges of MSK-NCDs

With an ageing population, the prevalence of MSK-NCDs such as osteoarthritis, osteoporosis, and rheumatoid arthritis has significantly increased. These conditions often result in chronic pain, reduced mobility, and a lower quality of life. “These diseases impact bones, joints, muscles, and connective tissues, leading to chronic pain and reduced mobility,” states project coordinator Arndt-Peter Schulz.

The SmILE project aims to tackle these challenges by integrating smart implants with digital health solutions to enable continuous monitoring and tailored recommendations.

A Smart Solution for Better Healthcare

At the core of the SmILE project is the development of a universal chip platform designed to transform medical devices into active data generators. This allows for real-time data collection, enabling quicker and more precise diagnoses while facilitating advanced treatment strategies.

The collected data will be processed through an integrated patient-centred health platform tailored to the needs of elderly users. This digital ecosystem will empower patients with a comprehensive overview of their health status, personalized recommendations, and active condition monitoring.

Additionally, an AI-driven data system will integrate patient information with real-time inputs from implants, wearables, and health questionnaires. This robust data ecosystem provides valuable insights for both patients and healthcare providers, ultimately improving disease prevention and management.

NANBIOSIS’ Contribution to SmILE

U23-S02. Embryo culture media viability studies

Embryo culture media viability studies

Through this service, and through the time-lapse incubator that we have, embryonic development studies can be carried out by enriching the culture media with different compounds or additives to later verify which of them produces better embryonic development and better quality of the embryos, through viability and embryokinetic studies.

Customer benefits

Because our laboratory is one of the few that does research in assisted reproduction with animal models and has all this equipment, in addition to a bank of gametes and cryopreserved embryos, human reproduction clinics that wish to carry out tests with culture methods for oocytes or embryos, they can only be done with animal species, so our laboratory is suitable for this. In addition, the studies can also be carried out under regulatory requirements, since the institution that carries them out is certified in Good Laboratory Practices.

In this way, preclinical studies can be carried out in animal models in compliance with the strict guidelines of the regulatory agencies, ensuring the reliability and traceability of all the results and tests carried out in its different services.

Target customer

This unit can provide services to all those companies that want to carry out quality control for Human Reproduction clinics, studies of in vitro fertilization and viability of embryo culture media, of mouse embryos or other animal species, whether that we have piezo electric. Furthermore, as we have a bank of cryopreserved mouse oocytes and embryos, any company that needs to have a large number of these gametes and embryos can benefit from this service.

U23-S01. In vitro fertilisation studies and embryo culture media viability

In vitro fertilisation studies and embryo culture media viability

Through this service, in vitro fertilization processes can be carried out, including IVF and ICSI, of oocytes and sperm from different animal species, including mice, which are the animal species we mainly work with. To carry out this fertilization we have cabins, heated laminar flow, with stereomicroscopes included, plates, incubators with different gas systems and in order to evaluate the development of the embryos in real time we have recently incorporated a time lapse incubator, which allows us to carry out embryokinetic studies without having to remove the plates and the embryo from the incubator which improves the quality and viability of the embryo.
