Development and regeneration of the neonatal digit tip in mice.
The digit tips of children and rodents are known to regenerate following amputation. The skeletal structure that regenerates is the distal region of the terminal phalangeal bone that is associated with the nail organ. The terminal phalanx forms late in gestation by endochondral ossification and continues to elongate until sexual maturity (8 weeks of age). Postnatal elongation at its distal end ...
متن کاملExpression pattern of Irx1 and Irx2 during mouse digit development
Irx1 and Irx2 are members of the murine Iroquois homeobox (Irx) gene family. In this study, we describe the dynamic expression pattern of these genes during limb development with a focus on digit formation. We further present a comparative expression analysis with Gli genes (Gli1, Gli2, Gli3). Gli1, Gli2, and Gli3 were suggested for candidate regulators of the Irx genes. The expression was stud...
متن کاملGDF5 coordinates bone and joint formation during digit development.
A functional skeletal system requires the coordinated development of many different tissue types, including cartilage, bones, joints, and tendons. Members of the Bone morphogenetic protein (BMP) family of secreted signaling molecules have been implicated as endogenous regulators of skeletal development. This is based on their expression during bone and joint formation, their ability to induce e...
متن کاملInter-digit HMM: connected digit recognition using the Macrophone corpus
Continuous digit recognition over the telephone channel is a key technology for many telecommuncations applications such as voice dialing, automatic banking, and credit card number entry. Speech recognizers usually acheive high performance by modeling the acoustics in Hidden Markov Models (HMMs) using large numbers of multivariate Gaussian mixtures with assumed diagonal covariance in order to m...
متن کاملHandwritten Digit Classification
The aim of this project was to evaluate the effectiveness of various types of classifiers in recognizing handwritten digits. It has been shown in pattern recognition that no single classifier performs the best for all pattern classification problems consistently. So the goal of the project was to experiment with different classifiers and combination methods and evaluate their performance in thi...
