nodulosus to a parasitic procercoid are studied and the development of all specialized systems (tegumental, muscular, excretory, nervous and glandular) are described and compared. As a consequence, the general cytological mechanism of differentiation has been identified in T. nodulosus. The cyto...
Each lung is comprised of many fine branching tubes, called 6 that end in tiny clustered chambers called 7. Rib muscles and the muscular 8 below the lungs operate the lungs like bellows, drawing air in and forcing it out at regular intervals....

Most adult organs contain regenerative stem cells, often organized in specific niches. Stem cell function is critical for tissue homeostasis and repair upon injury, and it is dependent on interactions with the niche. During ageing, stem cells decline in
This review will discuss recent advancements on different types of stem cells that have been attributed to be endowed with muscle regenerative potential. We will discuss the nature of these cells and their advantages and disadvantages in regards to therapy for muscular dystrophies. 展开 ...
INTRODUCTION: Nematostella vectensis, a member of the cnidarian class Anthozoa, has been established as a promising model system in developmental biology, but while information about the genetic regulation of embryonic development is rapidly increasing, little is known about the cellular organization of ...
Here, we report that position control genes (PCGs) that control regeneration and tissue turnover are expressed in a subepidermal layer of nonneoblast cells. These subepidermal cells coexpress many PCGs. We propose that these subepidermal cells provide a system of body coordinates and positional ...
and there is evidence for the presence of stem cells in ‘solid cell nests’ thought to represent the original remnant tissue.53In the World Health Organization classification system for endocrine neoplasms of domestic animal species, they are listed as C-cell neoplasms ‘derived from less different...
Among the many cell types of the immune system, natural killer cells (NK cells) are one of the earliest cell types to arrive at target organs of inflammation1. The role of NK cells in modulating inflammatory responses in different organs is often complex, not always com- pletely understood ...
7. While it has been known that the accumulation of senescent cells in the tissues of the elderly is related to tissue aging, it does not constitute the majority of cells within the tissue1,2,3,4,5. Moreover, it is understood that non-senescent cells within the elderly tissue still ...
