We have developed a new algorithm for ordering anterior chamber OCT images in such a way that it is possible to classify them, in a fully unsupervised manner, in meaningful groups according to relevant features. We have tested the algorithm with a large set of images classified by two expert ophthalmologists, and with a larger set of annotated images. We have verified that the separation in the different classes defined by the ophthalmologists (closed, narrow, open, and wide open_ figure 6) is similar when using the manually extracted features, or when using the features that are returned by the unsupervised algorithm (View figures). Therefore, the abstract features generated by the algorithm provide novel tools for assessing OCT images of the anterior chamber. They can be used for direct classification of the images and, furthermore, they can be linked to established quantities used for characterizing diseased eyes (like chamber depth, iris-corneal angle) resulting in an automatic detection system. As the algorithm is fully unsupervised, it can be easily automated and set up in OCT imaging systems to aid technicians and doctors in an early diagnosis. The two main advantages of the algorithm demonstrated here over previous works are that it doesn’t need any ground truth or gold standard for training, and it does not rely on specific landmarks; thus, it can analyze images in which relevant landmarks are not visible or not easy to locate.

Mesenchymal Stem Cells (MSCs) are multipotent precursor cells with the unique capacity to self-renew, proliferation and transformation into specialized cells present in many body tissues, such as muscle, adipose tissue, fibroblasts, cartilage, tendons, and nervous tissue. They are also characterized by the ability to affect the immune system by secretion of compounds that support the immune response directed among others against bacteria and parasites. They have properties enabling the secretion of chemical compounds that stimulate the formation of new blood vessels. All these attributes make them applicable in regenerative medicine, transplantology and in the treatment of many diseases. The umbilical cord blood and Wharton’s jelly MSCs are the sources from which MSCs are obtained. Due to the small amount of MSCs in the starting material, it is necessary to lead in vitro cultures to obtain sufficient numbers of cells that can be administered to the patient. Methods of isolation and culture of mesenchymal stem cells, including the growth medium, play a crucial role in obtaining the appropriate biological material that guarantees therapeutic success. Therefore, continuous improvement of procedures for isolating and in vitro culturing of MSCs is extremely important. The subject of the offer is a method of culturing mesenchymal stem cells using secretions from carnivorous plants, which increase cell adherence and proliferation, counteract their transformation into specialized cells, therefore, they longer maintain their pluripotency.
