Hepatocyte has a round nucleus (N) with one or two nucleoli. Abundant glycogen (G, stained light purple) and lipid droplets (L, stained black) are included in hepatocytes.

Between hepatocytes, there is a small circular canal, bile canaliculi (BC) into which hepatocytes secret bile.

Space between hepatocyte plate is sinusoids (S) which are lined by endothelial cells and Kupffer cells (KC) which has a large nucleus and protrude into the sinusoid.

Hepatocyte (H) has a round nucleus (N) with one or two nucleoli.

Between hepatocytes, there is a small circular canal, bile canaliculi (BC) into which hepatocytes secret bile.

Space surrounded by hepatocytes is sinusoids (S) which are lined by endothelial cells (EN) and Kupffer cells (KC) which has a large nucleus and protrude into the sinusoid.

Space surrounded by hepatocytes (H) is sinusoids (S) which are lined by discontinuous endothelial cells (EN) and Kupffer cells (KC) which has a large nucleus and protrude into the sinusoid.

Between hepatocytes, there is a small circular canal, bile canaliculi (BC) into which hepatocytes secret bile.

Space between the hepatocyte and endothelial cells (EN) and Kupffer cells (KC) is the space of Disse (perisinusoidal space, blue triangles).

Another sinusoid lined by discontinuous endothelial cells (EN) and Kupffer cells (KC) is shown in this photo.

Many irregular microvilli (Mv) from hepatocytes project into the space of Disse (blue triangles).

Space between the hepatocyte (H) and endothelial cells (EN) and Kupffer cells is the space of Disse (blue triangles).

Sometimes, Ito cell with large lipid droplets (L) and small lipid droplets is found in the space of Disse (blue triangles).

Bile canaliculus (BC) is located between hepatocytes and several microvilli (Mv) from hepatocytes projected into it.

Hepatocyte includes peroxisome (P),  abundant rER, mitochondria (M) and glycogen particles (G)

The intestinal villi (red dashed circle) consisted of simple columnar epithelium and the lamina propria (LP) which is beneath the epithelium. Intestinal glands (IG) are observed and also composed of simple columnar epithelium with gland lumen inside.

The intestinal villi consisted of simple columnar epithelium with microvilli and the lamina propria (LP). Goblet cells (green arrows) can be identified by apical dark blue-stained mucous cup. The lamina propria (LP) beneath the epithelium is highly cellular loose connective tissue and lacteals (black stars) could be observed in the center of the villi.

This enlarged photo showed obvious simple columnar epithelium with microvilli (red brackets), covered the simple columnar epithelium ). Goblet cells (green arrows) can be identified by apical dark blue-stained mucous cup. Lacteals (black stars) in lamina propria could be observed in the center of the villi and it is lined by simple squamous epithelium. A capillary (C) was shown with red blood cells. Dilated basal-lateral intercellular spaces (black arrows) are seen at the base of the columnar epithelium.

This TEM image showed obvious simple columnar epithelium with microvilli (red brackets) and goblet cells (green triangles). Goblet cells can be identified with a large accumulation of mucinogen granules in the apical cytoplasm. Dilated basal-lateral intercellular spaces (red stars) are seen at the base of the columnar epithelium. A capillary (C) was shown with red blood cells.

This TEM image showed the nucleus of goblet cell (green star) is located at the basal portion of the cell and the major part of the cell is a large accumulation of mucinogen granules in the apical cytoplasm (green triangles). Few microvilli of goblet cells (green arrows) are also presented on its surface. Abundant regular microvilli (red bracket) of absorptive cells are also observed.

The major part of the goblet cell is a large accumulation of mucinogen granules in the apical cytoplasm (green triangles) and few microvilli (green arrows) are also presented on its surface. Abundant regular microvilli (red bracket) of absorptive cells and terminal web (TW) are also observed.

Abundant regular microvilli (red bracket) of absorptive cells and terminal web (TW) are observed. Mitochondria (Mt) are seen in the photo.

Abundant regular microvilli (red bracket) of absorptive cells and terminal web (TW) are observed. Each microvillus has vertically-oriented actin microfilaments which extend into the apical cytoplasm and insert into the terminal web. Mitochondria (Mt) are seen in the photo.

The nucleus of goblet cell (green star) is located at the basal portion of the cell and the accumulation of mucinogen granules is in the apical cytoplasm (green triangles). Extensive rER and mitochondria (Mt) are also found in the basal cytoplasm.
