Clonogenic Neoblasts and Planarian Regeneration: An Example of Stem Cell-Mediated Epimorphosis
Clonogenic neoblasts are involved in planarian (flatworm) regeneration. This is an example of: (1) epimorphosis (2) morphallaxis (3) stem cell-mediated regeneration (4) compensatory regeneration Planarians, a group of flatworms, exhibit […]
Effects of Global β-Catenin Overexpression in Hydra: Induction of Ectopic Buds and Axes
In case of Hydra, the major head inducer of the hypostome organizer is a set of Wnt proteins acting through the canonical β- catenin pathway. What would be the result, […]
Role of Wnt/β-catenin Pathway in Axis Formation During Hydra Morphallactic Regeneration
Hydra shows morphallactic regeneration and involves which one of the following signal transduction pathway in its axis formation? (1) Wnt/β-catenin pathway (2) Retinoic acid pathway (3) FGF pathway (4) Delta-Notch […]
Morphallaxis Explained: Tissue Repatterning with Minimal New Growth in Regeneration
In case of morphallactic regeneration: (1) there is re-patterning of the existing tissues with little new growth (2) there is re-patteming of the existing tissues after the stem cell division […]
Hydra Regeneration: Morphallaxis as the Mode of Development Through Tissue Repatterning
If hydra is fragmented into various parts, separate group of cells re-pattern themselves into various small hydra. Such an mode of development is termed as (1) Regeneration (2) Morphallaxis (3) […]
Definition of Morphallaxis: Regeneration by Reorganization of Existing Cells
Morphylaxis can be defined as (1) Production of lost organ by division in remaining cell (2) Re-initiation of cell division in existing cells, followed by re-patterning of those cells (3) […]
Morphallaxis in Hydra: Repatterning of Existing Tissue for Complete Regeneration
In hydra if any part is lost remaining portion re-pattern itself and give rise to complete organism. Such a pattern of regeneration is termed as (1) Epimorphosis (2) Morphallaxis (3) […]
