Although several robust and sensitive methods for histamine detection are already available, it continues to be a challenge to develop simple and portable devices. that allows for 3D growth of cells. New citations to this author. Introduced in the early 1970s, hydrogel lenses made contact lens wear much more popular because they typically are immediately co. However, most currently available three-dimensional techniques are time consuming and/or lack. Conclusion: Our findings strongly indicate that SOX2 contributes to anchorage-independent growth and chemoresistance via its downstream signaling mediator AKT kinase during the disease progression of NSCLC.
