Sacrifice a embryo at the blastocoel stage. Obtain the stem cells from the blastomere.
they produce bacteria
No. Germ cells are needed to produce sperm. Sertoli cells only aid in the process.
So far as nuclear division is concerned, in somatic cells it is mitotic whereas in germ cells it is meiotic.
Muscle tissues are derived from the mesodermal layer of the embryonic germ cells through a process called myogenesis.
It develops from the endoderm germ layer
they produce bacteria
gametes
they produce bacteria
Ectoderm, endoderm, and mesoderm can produce epithelial tissues
gametes
Preembryonic forms are the zygote (fertilized egg), morula (a solid ball of cells), blastocyst (hollow ball with a single germ layer), and bilaminar embryonic disc(with two germ layers).
No. Germ cells are needed to produce sperm. Sertoli cells only aid in the process.
Osteocytes and osteoblasts produce more bone and bone matrix but cannot divide.Osteoprogenitor cells are germ (stem cells) found in embryonic cartilage and specialise in the presence of human growth factors into osteocytes / osteoblasts and other associated cells to produce bones.No specialised cell retains the capacity to reproduce itself independently

a group of specialized cells forms tissue, a group of tissue forms an organ
