Pacemaker cells and Purkinje fibres in the conduction system are specialized cardiomyocytes that generate and conduct electrical impulses. The sinoatrial node (SAN), which is composed of a group of pacemaker cells, resides in the right atrium generating impulses to initiate heart contraction. The atrioventricular node (AVN) is located between the atria and ventricles, and it conducts an electrical impulse from the atria to the ventricles. Mei Xin,
The origin of embryonic stem cells. Embryonic stem cells are grown from cells found in the embryo when it is just a few days old. In humans, mice and other mammals, the embryo is a ball of approximately 100 cells at this stage.It is known as a blastocyst and has two parts:1  An outer layer of cells, or trophectoderm, will form the placenta that supports the embryo as it grows inside the uterus. 2  An inner clump of cells, called the inner cell mass, is a ball of 10â20 cells. 3  These cells are undifferentiated, or unspecialized.t is known as a blastocyst and has two parts: 1  An outer layer of cells, or trophectoderm, will form the placenta that supports the embryo as it grows inside the uterus. 2  An inner clump of cells, called the inner cell mass, is a ball of 10â20 cells. 3  These cells are undifferentiated, or unspecialized.
