- LifeTime aims to track, understand and target human cells during the onset and progression of complex diseases and their response to therapy at single-cell resolution. This mission will be implemented through the development and integration of single-cell multi-omics and imaging, artificial intelligence and patient-derived experimental disease models during progression from health to disease. Analysis of such large molecular and clinical datasets will discover molecular mechanisms, create predictive computational models of disease progression, and reveal new drug targets and therapies. Timely detection and interception of disease embedded in an ethical and patient-centered vision will be achieved through interactions across academia, hospitals, patient-associations, health data management systems and industry. Applying this strategy to key medical challenges in cancer, neurological, infectious, chronic inflammatory and cardiovascular diseases at the single-cell level will usher in cell-based interceptive medicine in Europe over the next decade.

- The serum concentration of hyaluronan (HYA) was determined in 59 patients with various myeloproliferative disorders, including 33 patients with idiopathic myelofibrosis. In 18 patients the serum concentration of the aminoterminal propeptide of type III procollagen (PIIINP) was measured concomitantly. Raised serum HYA levels were seen in patients with active disease compared with age-matched healthy subjects, whereas no significant difference in serum HYA was seen between patients with stable disease and age-matched controls. Serum HYA concentrations correlated significantly with the leukocyte count (rho = 0.38; P less than 0.02) and with the serum concentration of PIIINP (rho = 0.50; P less than 0.001). During cytotoxic treatment, the serum HYA and PIIINP concentrations decreased in concert with declining leukocyte counts. These findings suggest that clonal expansion is accompanied by a bone marrow stromal reaction similar to the repair processes following injury to soft connective tissues. The relatively modest changes in serum HYA with frequent overlaps between patient categories and healthy subjects imply that the clinical utility of single determinations of serum HYA in the present disease groups is restrained. On the other hand, sequential measurements of HYA may provide a reflection of the myeloproliferative process in individual patients.

- In the course of development of a new type of filler for the correction of small defects in soft tissues we studied macroporous gelatine spheres as culture substrate, transplantation vehicle, and biodegradable scaffold for guided regeneration of soft tissues in vivo. We injected intradermally in nude mice gelatine spheres that had either been preseeded with human fibroblasts or preadipocytes, or left unseeded. We compared the extent of regenerated tissue with that found after injections of saline or single-cell suspensions of human fibroblasts or preadipocytes. Routine histological examinations and immunohistochemical staining for von Willebrand factor (indicating neoangiogenesis) were made after 7, 21, and 56 days. Injected saline or single-cell suspensions had no effect. However, a quick and thorough tissue regeneration with developing neoangiogenesis was elicited by the gelatine spheres and the effect of spheres preseeded with preadipocytes surpassed the effect of spheres preseeded with fibroblasts, which in turn surpassed the effect of unseeded gelatine spheres. We suggest that minor soft tissue defects such as wrinkles or creases can be corrected by injection of naked macroporous gelatine spheres, whereas larger defects are best corrected by injection of macroporous gelatine spheres preseeded with fibroblasts, or preadipocytes, or both.
