The spongy trabecular bone provides mechanical support while maintaining a low weight. A correct measure of its mechanical properties at the tissue level, i.e. at a single-trabecula level, is crucial for analysis of interactions between bone and implants, necessary for understanding e.g. bone healing mechanisms.

Introduction Prevalence and Impact. Glaucoma is the second leading cause of blindness in the world. Its current worldwide prevalence in the population aged 40-80 years old is estimated to be 3.54% with the highest incidence in the African and Asian racial groups. Glaucoma is projected to affect 76 million people by 2020 and 111.8 Million in 2040.

Since trabecular bone has a heterogeneous microstructure, a certain area is needed in order to assume it to be a continuum. Linde et al 66 reported that the elastic modulus is directly proportional to specimen cross section (up to a diameter of 7.5 mm or a side length of 6.5 mm) and aspect ratio.

The trabecular meshwork (TM), the tissue that primarily regulates intraocular pressure, is known to have reduced cellularity in glaucoma. Thus, stem cells, if properly delivered to the TM, may offer a novel therapeutic option for intraocular pressure control in glaucoma patients. For this purpose, targeted delivery of stem cells to the TM is ...
