| Primary mesenchyme cells introduced by injection at the animal pole move in a directed manner to their normal positions in the vegetal region. |
|
| The lenticular process is actually derived from mesenchyme attributed to the second branchial. |
|
| The mesoderm also provides the mesenchyme from which organ development becomes possible. |
|
| The intervertebral discs develop embryologically from both the mesenchyme and the notochord. |
|
| The subcoelomic mesenchyme is defined as the layer of tissue that lies underneath the mesothelial surface of the peritoneum. |
|
| One type tends to form surface tissues or epithelium, the other becomes mesenchyme, the tissue that holds us together and becomes blood vessels. |
|
| Fertilization occurs in the mesenchyme and the zygotes develop into ciliated larvae. |
|
| The mammary glands also develop under sequential reciprocal interactions between the epithelium and adjacent mesenchyme. |
|
| These are lined by a thick layer of nasal epithelium surrounded by the mesenchyme of the placode. |
|
| Derived from embryonic mesoderm, mesenchyme is the first connective tissue formed. |
|
| These include the epidermis and inner tunic and some mesenchyme derivatives which have differentiated into blood cells in the larva. |
|
| The branchial arches begin as cylindrical cores of mesenchyme sandwiched between continuous sheets of epidermal ectoderm and internal endoderm. |
|
| Mutations that disrupt the signaling interactions between epithelium and the underlying mesenchyme can cause eyelid closure defects. |
|
| The critical process depends upon whether the ectoderm can contact a condensate of specialized mesenchyme called the dermal papillae. |
|
| There is some mesenchyme in the core toward the base, however, they are very different in structure. |
|
| Activates the lymphatic system in order to detoxify the connective tissues and the mesenchyme. |
|
| This necrotic zone induces the differentiation of fibroblasts towards the pulp and undifferentiated mesenchyme cells to form hard tissue cells. |
|
| Connective tissue is a mesenchyme that fastens together other more highly organized tissues. |
|
| The rudiments of blood vessels are always aggregations of mesenchyme cells. |
|
| The mesenchyme forms blood and lymph vessels, the heart, and the loose cells of connective tissues. |
|
|
|
| In tetrapods, however, the limb muscles develop from the same mass of mesenchyme that gives rise to the skeleton. |
|
| The ridge protrudes into the coelomic cavity, and the fold of thickened epithelium becomes filled with mesenchyme. |
|
| What's more, these commands are part of the developmental vocabulary of mesenchyme cells generally, and are understood in more or less the same way throughout the embryo. |
|
| That of course takes the problem back in time as to where or what organized the collagenous lattice in the dermal mesenchyme, but let's not get into that. |
|
| Other matrix proteins, such as fibronection, are also present throughout developing lung mesenchyme and at tips of secondary septae in the alveolar stage. |
|
| The mesenchyme is penetrated by proliferating buds that arborize and terminate in acini. |
|
| Beginning at that time, the number of mesenchyme cells migrating into the blastocele was increased above normal levels. |
|
| Estradiol and bisphenol A stimulate androgen receptor and estrogen receptor gene expression in fetal mouse prostate mesenchyme cells. |
|
| Since malignant tumors that originate in the mesenchyme are very rare, the differential diagnosis is difficult. |
|
| The dermal papilla is a highly active group of cells, and it is derived from the dermis mesenchyme, located at the base of the hair follicle. |
|
| The term pulmonary 'hamartoma' is nosologically incorrect since this lesion is probably a benign neoplasm, derived from bronchial wall mesenchyme. |
|
| The parietal layer of the somite, at a later stage, is converted into mesenchyme that, together with components of the neural crest, gives rise to the dermis of the skin and, for this reason, is called the dermatome. |
|
| The lower, medioventral part of the somite, called the sclerotome, breaks up into mesenchyme, which contributes to the axial skeleton of the embryo that is, the vertebral column, ribs, and much of the skull. |
|
| Primary mesenchyme cells, or PMCs, are located in the vegetal plate specified to become mesoderm. |
|
| Cranial skeletogenic mesenchyme is derived from two distinct embryonic sources, cephalic paraxial mesoderm and cranial neural crest. |
|
| The porous nature of the mesenchyme permits accumulation of fluid. |
|
| Each fin develops an independent blastema through the condensation, and differentiation into osteoblasts, of undifferentiated mesenchyme in the medial part of the fin. |
|
| There remains for discussion the mesenchyme theory, which proposes that a mesenchymal schizocele evolved into a cavity lined by a typical ciliated epithelium. |
|
| The development of the mesentery starts when the foregut, midgut and hindgut are in broad contact with mesenchyme of the posterior abdominal wall in the fetus. |
|
| In kidney development, the metanephric cap mesenchyme contains a population of progenitor cells that give rise to nearly all of the epithelial cells of the kidney. |
