Conceptual advance and Impact5
The author describes vessel.like structures on rat abdominal organs that are blood filled. Observation looks interesting however it should be specified further by naming the specific organ author took the images. In one part it is said to be abdominal organ surface:intestine etc however in the Figure it is not clearly written.
Microscopic detection of a tubular-like structure possibly filled with erythrocytes and nodes of the primo vascular system in the organ surface of rats: Indications for extramedullary hematopoiesis
Could you please specify which organ is the one that you detected the vessel like structures is this intestine alone ?
(H-I)please specify the organ (in introduction it is mentioned to be the abdominal organ surface however there is no specification throught the text)
Do you think the white dots you observed on the intestine might be Payers patches?
Conceptual advance and Impact4
The article is appropriately structured for the ScienceMatters journal. I would suggest a correction of the title and objective using more precise language.
Please shorten the title to capture the essence of the article such as "Microscopic detection of the primo vascular system in rats" or similar.
"Indications for extramedullary hematopoiesis" is an overstatement based on the provided evidence.
Please state the objective in a clear and concise way. Only one sentence is relevant in this paragraph: "One objective of the research was to perform a detailed analysis of PVS specimens with phase-contrast microscopy and digital image analysis."
