This book presents essential information on the use of the immunodeficient C.B.-17 SCID/SCID mouse for studying human hematopoiesis in vivo. Because of the lack of both humoral and cellular immunity, this mouse can be a unique host for implantation of human hematopoietic tissue using different methods. In the first section, in vivo development of human hematopoietic stem cells and differentiation of human T cells are described. In addition, the effects of growth factors and toxic agents of human hematopoiesis are described. The second section contains chapters in which the human immune responses in the SCID mouse are reviewed. The third section covers SCID mouse models to study human infectious diseases, leukemias and genetic disorders.
In order to survive, bacteria must constantly monitor their structure and physiology. Adaptive behaviours are established by using environmental sensors and response regulators. These communication modules regulate a wide variety of signals including host detection and invasion, cell cycle, metabolite utilization, starvation and many others. The purpose of this volume is to give an overview of the various systems and to introduce recent advances in understanding selected systems of pathogenic bacteria.
The human liver is a dynamic organ throughout life, but no more so than during prenatal development. The liver performs many essential functions associated with metabolism, immunity and blood production. These diverse functions are performed by a variety of cell types that have the capacity for growth, allowing the liver to regenerate cells lost due to aging, infection or injury. Various stem cell populations are at the core of the liver's potential for regeneration, which are most active during embryonic and fetal development, when the liver undergoes rapid growth. Consequently, the prenatal liver represents a unique opportunity to study the precursor cells that give rise to all liver cells...
Stanley traces women's inventions in five vital areas of technology worldwide--agriculture, medicine, reproduction, machines, and computers.
Atherosclerosis, the most common disease in humans and also the main cause of death in the Western world, only develops after an intima is formed. The intima is defined as the region of the arterial wall from the endothelial surface to the luminal margin of the media. This volume considers all aspects of intima formation based on results which had been obtained by studying three different models: - Spontaneous intima formation; - Experimentally induced intima formation; - Latrogeneously induced intima formation.
