“…However, the sprouting pattern is a junction inside a single bone and can not be explained from a functional point of view. Schiwy‐Bochat (2001) reported that there is a sprouting‐only area in the supranasal region. We can produce a sprouting‐only pattern with our model (data not shown), and it would be intriguing to predict the change in gene expression by comparing the model parameters and actual patterns.…”

Skull sutures serve as growth centers whose function involves multiple molecular pathways. During periods of brain growth the sutures remain thin and straight, later developing complex fractal interdigitations that provide interlocking strength. The nature of the relationship between the molecular interactions and suture pattern formation is not understood. Here we show that by classifying the molecules involved into two groups, stabilizing factors and substrate molecules, complex molecular networks can be modeled by a simple two-species reactiondiffusion model that recapitulates all the known behavior of suture pattern formation. This model reproduces the maintenance of thin sutural tissue at early stages, the later modification of the straight suture to form osseous interdigitations, and the formation of fractal structures. Predictions from the model are in good agreement with experimental observations, indicating that the model captures the essential nature of the interdigitation process.

“…However to ensure that the AM information was correct, sex was determined, when possible, from each of the skeletons. As it was assumed that there would only be men among the skeletons, the sex determination was basically done by looking for female traits on the pelvic bones and the skull (13)(14)(15)(16)(17)(18)(19)(20). The absence of a clearly female pelvis or skull was taken as satisfactorily evidence of the individual being male.…”

This article presents the multidisciplinary effort in trying to identify the skeletal remains of 100 Norwegian soldiers serving in the German army, killed in Karelia Russia in 1944, from the recovery of the remains through the final identification using DNA. Of the 150 bone samples sent for DNA testing, 93 DNA profiles were obtained relating to 57 unique individuals. The relatives could not be directly contacted as the soldiers were considered as traitors to Norway; therefore, only 45 reference samples, relating to 42 cases of the missing, were donated. DNA matches for 14 soldiers and 12 additional body part re-associations for these individuals were found. Another 24 bone samples were re-associated with 16 individuals, but no familial match was found. More than six decades after the end of WWII, DNA analysis can significantly contribute to the identification of the remains.

“…Various methods have been proposed to classify and ⁄ or quantify the shape of human cranial interosseous sutures (Hauser et al 1991), and to use this information to infer sex and age at death of osteoarcheological specimens Mann et al 1987;Meindl et al 1990;Hershkovitz et al 1997;Schiwy-Bochat, 2001;Lynnerup & Jacobsen, 2003;Skrzat & Walocha, 2003;Sahni et al 2005;Wu et al 2007;Wittwer-Backofen et al 2008). Classification systems typically define different degrees of 'corrugatedness' of the suture line, while quantitative methods rely on fractal analysis.…”

A bidirectional interface growth model for cranial interosseous suture morphogenesis

Interosseous sutures exhibit highly variable patterns of interdigitation and corrugation. Recent research has identified fundamental molecular mechanisms of suture formation, and computer models have been used to simulate suture morphogenesis. However, the role of bone strain in the development of complex sutures is largely unknown, and measuring suture morphologies beyond the evaluation of fractal dimensions remains a challenge. Here we propose a morphogenetic model of suture formation, which is based on the paradigm of Laplacian interface growth. Computer simulations of suture morphogenesis under various boundary conditions generate a wide variety of synthetic sutural forms. Their morphologies are quantified with a combination of Fourier analysis and principal components analysis, and compared with natural morphological variation in an ontogenetic sample of human interparietal suture lines. Morphometric analyses indicate that natural sutural shapes exhibit a complex distribution in morphospace. The distribution of synthetic sutures closely matches the natural distribution. In both natural and synthetic systems, sutural complexity increases during morphogenesis. Exploration of the parameter space of the simulation system indicates that variation in strain and ⁄ or morphogen sensitivity and viscosity of sutural tissue may be key factors in generating the large variability of natural suture complexity.
